Season 1 (2016) 
1."Pilot"-In Coolsville, Ohio, a gang is about to do a job on a house led by a man named Colton Rogers. Colton is annoyed with how cowardly Scooby is and how annoying Scrappy is despite Scrappy being headstrong and always wanting to face off in a fight against problems towards the gang. On the way back, Scooby is accidentally left behind. Seeking shelter from a thunderstorm, he comes across a graveyard where he witnesses two ghosts rise from their graves. Scooby panics and runs away, ending up in the bedroom of Norville "Shaggy" Rogers, a clumsy and geeky outcast. The two quickly bond and Shaggy adopts Scooby. Later, Shaggy tries to smuggle Scooby onto the school bus, but a fight breaks out which causes the bus to crash into a flagpole, which falls on Vice Principal Grimes' car, smashing its windshield. Because of the fight on the bus and the damage to Grimes' car, Shaggy is sent to the library for detention, along with three others: Fred Jones, the quarterback of the football team; Velma Dinkley, a science nerd; and Daphne Blake, a wealthy student from New York City. They bond somewhat over a shared interest in mysteries, but quickly get on each other's nerves. Two ghosts suddenly appear and chase them to the gym where a pep rally is taking place. A third ghost, The Specter appears, causing the lights in the building to flicker. He starts telling everyone to leave. The stamp-collecting Principal Deedle decides to close the school, but Vice Principal Grimes deems it a prank and suspends the quartet as he refuses to believe that there are ghosts in the school. The gang then follows Scooby to the graveyard, where he saw the ghosts, to clear their names. At the graveyard, two suspicious graves (Prudence Prufrock and Ezekial Gallows) are found and Velma makes a rubbing of them. The next day, the kids meet up in Shaggy's basemant. Velma tells them about how the two graves were the founding faculty of the old school, which was wiped out in the Coolsville flood just before 1900. They decide to go looking for clues at the school that night. Once they arrive, Velma finds a sticky fluid beneath where the third ghost appeared. The ghosts of Ezekial and Prudence then posses two football mannequins and attack the group, who split up and are chased by the ghosts. Fred discovers another clue, the gymnastics harness, which would allow the specter to 'fly'. During the chase, Shaggy and Scooby are locked in the school's freezer, but the rest of the gang escapes as the school blow up, leaving Shaggy and Scooby's faiths unknown.
2."The Mystery Begins"-Velma, Freddy and Daphne return when they realize Scooby and Shaggy are gone. Grimes discovers the two in the freezer, along with a lot of damage caused to the school by the ghosts. Grimes is infuriated and expells the gang and threatens to press trespassing charges. Although the gang is expelled, Velma reveals the liquid they found can be used to make a smokescreen like the third ghost had used. Shaggy would later tell them about two possible suspects, Otis and the librarian. The gang comes back later in the school day wearing disguises to spy on the suspects. Fred and Daphne find out that Otis just wants to be a dance star. Velma not only finds out that the librarian got a transfer, but that Vice Principal Grimes checked out a book on raising the dead. The gang decides to go to Grimes' house, but they do not have a car or licenses to drive all the way to Coolsville Mountain where he lives. They take Daphne's gardener's old van, after Shaggy reveals he was held back and has his license (albeit he proves to be a still poor driver). Searching at night at Grimes' house, they find information about a time capsule in the book on raising the dead. The ghosts further attack, and the teens are knocked out by the Specter. They awake back at the school, where the Specter has blown a hole in the floor of the gym that leads directly into the old school (which was buried in the flood). The Specter, keeping Scooby and Grimes as prisoners, forces the gang to search underground for the time capsule. The gang goes down into the old school, but trick the Specter into coming down to carry the capsule out of the hole. Unfortunately, their plan backfires when they try to lock him up in a flooded room. The Specter steals back the capsule, but unleashes Ezekial and Prudence on them. As he looks for a spell to get rid of the ghosts, Shaggy accidentally releases more ghosts onto the town. Meanwhile, Scooby breaks free of his bonds. Shaggy eventually manages to banish the ghosts (who were not in control of their actions), and Scooby arrives jut in time to tie up the Specter. But when the gang unmasks the Specter, he turns out to be... Principle Deedle. He had wanted a rare misprinted stamp buried in the time capsule. After the exposed Deedle is fired from his job and is sent to prison for his actions, the gang is publicly congratulated by Grimes, who has re-enrolled them into Coolsville High. Grimes also apologizes to the gang for accusing them. Just as the gang begins digging to bury the Coolsville Academy time capsule, Shaggy accidentally throws his shovel onto Grimes’ car, once again smashing its windsheild. Instead of giving him another detention, Grimes forgives Shaggy. With the mystery over, there is nothing to bind the friends together anymore and they start to go their separate ways. Just then, Velma comes back and informs them of some "strange goings-on at the museum." They now set off to solve another mystery along with Scooby-Doo!
3."Beware of the Beast From Below"-Fred Jones Sr., Rachel Rogers, Nan Blake, Angie Dinkley, and Dale Dinkley become concerned about the"mystery" phase that their teens are going through right after Sheriff Bronson Stone arrests them for solving another mystery only for Fred Sr. to use his connections as mayor to get the charges dropped against them. A slime mutant that lives underneath Coolsville is cocooning anyone who gets in its way. Despite being warned not to continue investigating by their parents and authority figures, the gang attempts to solve the mystery. Meanwhile, Velma is trying to get Shaggy to be more intimate in their secret relationship. Daphne also keeps hinting her romantic feelings towards Fred who is oblivious to almost everything apart from solving mysteries and building traps. The Slime Mutant lurked below Crystal Cove and attacked people underground. After a confrontation with it underground, Mystery Incorporated eventually caught it, taking off its mask to reveal Prof. Emmanuel Raffalo underneath. Their teacher was using passageways from Fruitmeir's to the sewer system to steal from the Crystal Cove Bank. During the investigation, Daphne locates a locket shaped similar to a magnifying class. Fred Sr. seems to recognize it and gets angry at Daphne for finding it. After solving the mystery the gang comes into contact with a mysterious man who refers to himself as "Mr. E" and remarks that they have uncovered "a truth that should have remained hidden" and that "the real mystery has just begun".
4. "Survive The Night"-Mr. E sends the gang to investigate the 75-year-old disappearance of the Darrow family and their mansion, they find themselves trapped in the underground Darrow Mansion, which has many booby-traps. What they do not know is that they are not alone inside the Darrow Mansion, and that someone is trying to kill them, in order to protect something which the original Mystery Incorporated was looking for. When the gang discovered a way down to the mansion, Danny Darrow (Danny Devito), a survivor of the Darrow family mistakes the gang for the original Mystery Incorporated (Brad Chiles, Judy Reeves, Rick Owens, Cassidy Williams, and Pericles) as he believed Fred Jr. to be Brad and Daphne to be Judy, and he tried to trap and kill them. They manage to escape, and eventually Darrow realizes they were not who he thought they were. Darrow honorably them the puzzle piece and lets them escape, just as the ground around the mansion begins collapsing again, leaving his fate ambiguous. In the end, the gang solves the mystery and they collect a strange puzzle piece, which they believe might be cursed and that is essentially one of the key elements of that mystery, vowing to find out what exactly is the story behind it. The gang also wonders what to consider of Mr. E as Mr. E nearly cost them their lives by making a crazy old hermit target them. The gang is unaware of this, but Fred Sr. is seen watching them leave the Darrow mansion and is largely upset by all this.
5,"Revenge of The Man Crab"-Dylan and Brenda are on Crystal Cove State Beach to prepare volleyball courts for an upcoming tournament sponsored by the Trickell's Trickquid beverage company. The two are arguing because Dylan wants to ensure everything is correctly set up while Brenda wants to leave early. Suddenly, a giant crab-like beast appears, grabbing Brenda and pulling her beneath the sand as she scream about a "Man-Crab." At first, Dylan thinks it's a joke or ploy to get him to leave early, but he grows concerned when Brenda doesn't come back out of the sand. The Man-Crab bursts out of the sand again and hovers over a terrified Dylan. The gang arrive at the tournament and are acknowledged by Angel Dynamite, who is broadcasting live from the event. They also see the costumed Trickell's Trickquid mascot, marketing the company's signature "non-fat liquid diet no calorie gluten-free moisture supplement." Shaggy and Scooby-Doo state they want "real food" and go to get clam cones from Skipper Shelton's Clam Cabin. Velma ignores Shaggy's advice and asks Skipper Shelton about his missing nose, which causes Shelton to rant about a clam that attacked him. When Shaggy tries to order, Velma pressures him about his diet and tells him to cut down on junk food. Shaggy - trying to please Velma - backs out of his clam cone order, baffling Scooby. Fred suggests that he and Daphne get clam cones, but she reminds him about her severe seafood allergies. Fred asks Skipper Shelton why his restaurant has moved and Shelton angrily states that Fred Sr. forced him to relocate the Clam Cabin from its regular spot every time there is an event on the beach. As the tournament begins, Velma tries to sit with Shaggy but is thwarted by Scooby, who sits down between them. Daphne sits with Fred and is upset by his apparent fixation on the women in the tournament until Fred, still clueless to Daphne’s interest in him, explains that he’s interested in the volleyball net and how great it would be in a trap. Suddenly, a massive crab arm rises out of the sand, catching and popping the volleyball. The rest of the Man-Crab rises from the sand soon after, chasing the players and destroying the court. Spectators flee as the Man-Crab moves towards the stands and chases the gang and a nearby group of children. After being sent airborne by one of the Man-Crab’s attacks, the gang and children are saved by some of the tournament players using a piece of Volleyball net. Angel tries to stop the monster by throwing sharpened CDs at it, but the creature ricochets them back towards Angel and attacks her booth. The Man-Crab grabs a female player and drags her through the sand. Chased by the gang, Man-Crab takes the player into a tent where they both disappear. Fred Sr. wants to keep the tournament open despite the dangers and is delighted when Sheriff Bronson Stone states that he can't handle the man-crab and that the games should continue. Fred begins to slowly realize how selfish his father truly is. The gang decide to make their own investigation and quickly find a locker bearing the name Skipper Shelton, which is spilling sand. Realizing that Shelton was not around during the Man-Crab attack and his frustration about being forced to move his restaurant would give him a motive, the gang begin to suspect him. Daphne suggests that Fred set a trap, though Fred doesn’t pay attention to her and announces moments later that he’s decided to set a trap. He asks her about her experience playing volleyball and Daphne downplays her skill, remembering how bad of a player she is. Excited, Fred reveals that she’ll be the perfect bait. Shaggy and Scooby are given lookout duty while Fred works on his trap. Shaggy struggles with trying to please Velma in his change of diet, which arouses suspicion from Scooby. Fred unveils his simple plan: Daphne will lure the Man-Crab across a spring loaded door buried in the sand. Once released, the door will launch out of the sand and seal the Man-Crab into a large metal pot. Velma goes to get Daphne and finds that she has changed into a bikini. Daphne, desperate to attract Fred’s attention, asks Velma to rub sun tanning oil on her back because, "Fred likes shiny things." Velma takes the opportunity to ask Daphne for relationship advice, but Daphne reacts thinking that one of her sisters told Velma about her interest in Fred. After Daphne realizes that Velma doesn't know anything about that, she calms down. Getting back to her original question, Velma asks whether boys like to be told what to do. Replying that they do, Daphne recounts stories about her parents. While they talk, the Man-Crab sneaks up and knocks Velma into the Mystery Machine while Daphne’s back is turned. After the Man-Crab uses the tube of oil to drench Daphne, she turns around and screams for help. Meanwhile, Shaggy finds it hard to avoid the Clam Cabin. When Scooby offers to keep it a secret, Shaggy runs to get a clam cone but accidentally triggers Fred’s trap, sealing himself in the pot. Daphne runs to Fred’s trap as planned but finds it already sprung. With nowhere else to run, she is pulled into the sand by the Man-Crab. Horrified, Fred starts digging furiously in the sand where he last saw her. Velma tries to calm him down, but Fred continues digging while talking manically about not knowing what to do. That night at K-Ghoul, Fred kneels on the floor and continues his digging motions. Velma explains to Angel that he hasn’t stopped since Daphne disappeared and has torn up the carpet in the back of the Mystery Machine. Shaggy blames himself for Daphne’s capture, stating that it wouldn't have happened had he never tried to be healthy. Scooby delivers giant platters of food to Shaggy, who is eating to drown his sorrows. Fred briefly stops digging to ask why someone hasn’t made a plan. Reminded by Velma that he is the one who makes the plans, he calls out "What's wrong with me!?" and immediately returns to digging. The station’s doorbell rings and Scooby finds a letter from Mr. E on the doorstep, containing an old torn up newspaper article about four kids who disappeared in the Crystal Cove Caves and a brief 8-Track tape message suggesting they investigate it. Fred, still out of sorts, tries to play the tape on a record player. Angel urgently asks to see the torn newspaper piece, but denies any knowledge of the incident after seeing it. Velma, Shaggy, Scooby, and Fred go to Crystal Cove Library to look for more information about the four kids who vanished in the caves. Fred continues to nervously chatter, pointing out irrelevant things and relating them to Daphne. Velma uses a computer station to pull up newspaper articles about Trickell's Trickquid, Skipper Shelton, and the missing kids. Realizing that the caves run under the beach where the volleyball tournament is being played, they go to the caves to investigate. Shaggy spots an enormous wooden stairwell leading to a trapdoor in the roof of the cavern. Velma notes that an actual crab monster wouldn't need a stairwell to navigate the caves. After Fred interrupts to talk about Daphne again, he hears Daphne call out to him. Hearing her voice, Fred continues to say whatever pops into his mind about Daphne, which include near professions of love. Following her voice, the gang find a cage with Brenda, Dylan, Daphne and the volleyball player. Fred quickly returns to normal after locating Daphne. After everyone is set free, the Man-Crab arrives and a wild chase ensues. With the Man-Crab right behind them, Shaggy and Scooby frantically climb the wooden stairwell and go through the trap door. Finding themselves in the middle of the beach volleyball courts and still being chased by the Man-Crab, they race towards Fred's original trap and successfully set it off to catch the monster. Fred, Daphne, and Velma arrive at the trap with Sheriff Stone and his deputies. Shaggy amazes Velma by revealing that he and Scooby found their way out of the cave and back to the trap using the smell of the Clam Cabin. Fred goes to unmask the Man-Crab believing it's Skipper Shelton, but he suddenly arrives on the scene. Velma surprises everyone by reaching into the suit and pulling out Bud Shelton, the man dressed as the Trickell's Trickquid mascot. Velma explains that she knew it couldn’t have been a real crab, since Daphne never had an allergic reaction around it. Additionally, she states that she recognized Bud from a photo in the newspaper article about Trickell's Triquid they found at the library. Bud reveals that Trickell's Trickquid was his creation and that he terrorized the tournament to take revenge on Peter Trickell for taking credit for it. He planned to deflect the blame by storing the Man-Crab disguise in a locker made to look like it was Skipper Shelton's. Daphne asks Bud why he didn’t simply get a lawyer and sue and he replies that lawyers take too long. The gang hang out in the K-Ghoul lounge while Angel works in the broadcast booth. Velma sits with Shaggy and Scooby, clearly displeased as they messily feast on a massive platter of waffles. Daphne approaches Fred and says that Velma told her that her disappearance bothered him. After she tells him that she appreciates it, Fred nervously downplays his behavior, stating that he’s glad it won't mess up their friendship and that he "will never have feelings again." Believing that Fred likely reciprocates her feelings, Daphne keeps smiling and knowingly says "we'll see." Daphne then asks Velma if she missed anything else while she was gone, prompting Velma to show her the newspaper clipping from Mr. E. Seeing the paper clipping, Daphne gasps and pulls out the locket she found in the caves, putting them side-by-side: the two kids in the locket photo are two of the kids that disappeared. Intrigued at the connection, Velma announces that they’ve got another mystery to solve. Unknown to the gang, Angel listens in on their conversation through the station’s soundboard and appears concerned by their attention turning to the story of the missing kids.

District Attorney Janet Nettles interviews them and reluctantly decides that the gang is being sincere which is why she convinces Bronson to give them a chance to catch the actual culprits with Fred and Daphne posing as a couple which awkwardly leads to the two of them having feelings for each other. The culprit is then revealed to be Chasez, he formed the gang's evil impersonators (Chasez dressed up in an "evil" Scooby-Doo mask and costume) and went around Coolsville framing them because he was outraged about how much time Rachel was spending with Shaggy. Later, after the police and the Mystery Gang went to his cabin to find the missing teenagers, J.C was quickly attacked by the mob of teens who recognized him, with Rachel in vain trying to protect him. One of the teens ripped off a piece of his shirt and hair, much to his discomfort, to which the police got him into a police car for protection. Rachel is left touched by Chasez's motive to this.

Fred Sr. denies this claim by arguing that when Pericles was arrested some time ago, he confiscated the second puzzle piece for safe keeping since he was a young city councilman at the time. Velma later learns that Pericles was implicated some time ago for the disappearance of the original Mystery Incorporated although Pericles would deny it.
