Beware the Beast from Below is the first episode of the first season of Scooby-Doo! Mystery Incorporated.


Defying their parents, who see their friends as bad influences, and the local authorities, who aren't happy being undermined, the teenage sleuths take on another case: a slime mutant that lives underneath Crystal Cove is cocooning anyone that gets in its way.


The gang celebrate a freshly-solved mystery, but are locked up by Sheriff Stone and lectured about meddling in police affairs. The sheriff informs them that he has called their parents to come get them and places special emphasis on having called Fred's dad: Crystal Cove's Mayor, Fred Jones, Sr. After Stone leaves, the gang lament that no one appreciates them for solving the town's mysteries.

Velma leads a tour of the Crystal Cove Spook Museum, unenthusiastically recalling major legends of the supposedly cursed town: the centuries-old disappearances of Spanish Conquistadors and Spanish Missionaries, as well as the more recent disappearance of the Darrow Family. Tourists become enthralled with displays of famous Crystal Cove ghosts like Space Kook and Captain Cutler, but this prompts Velma to cynically reveal that almost all of these so-called ghosts were just criminals in costumes. Velma is quickly stopped by her parents with a hand over her mouth, who get the tourists to forget about the spoiled ghost legends by reminding them of the museum gift shop. As soon as the tourists are gone, Velma and her parents argue: Velma is adamant that she's right in being honest with the tourists, while her parents view the information as a threat to their Curse of Crystal Cove themed museum.

Meanwhile, the other members of the gang also argue with their parents. Mayor Jones wants his son to be a role model in the community; Fred says that he tries make his dad proud but also insists that there's nothing wrong with wanting answers. Shaggy's parents tell him that they want him to find new friends; Shaggy insists that he and Scooby-Doo are never in danger and his friends need to be given a chance. Daphne's parents are concerned about her interest in Fred; Daphne insists that the gang, and especially Fred, are just misunderstood. After being unfavorably compared to her successful sisters, Daphne hears the Mystery Machine's horn and hurriedly says good-bye to her family before leaving for school with the gang.

Meanwhile, three sewer workers accidentally open a passage into the Crystal Cove Caves and find barrels with toxic warning signs. Opening one to inspect it, they scream as a green substance bursts out at them. Still on the way to school, Velma prods Shaggy about their secret relationship and his reluctance to show any affection for her in public. After she tries to kiss him, Shaggy anxiously confesses that he's worried Scooby won't understand and is waiting for the right time to talk with him. Impatient, Velma immediately turns to tell Scooby but is cut off when a manhole cover explodes off of the road ahead, forcing Fred to slam on the brakes. With fog pouring from the open manhole, the Slime Mutant emerges and attacks the Mystery Machine before disappearing back into the fog.

The gang locate the cave entrance made by the workers and search for clues. Daphne finds a magnifying glass shaped locket with a question mark on it containing a picture of a teen couple. After Fred compliments her, she turns to acknowledge him but is disappointed that he's already walked away. Shaggy soon finds a hard hat, prompting Scooby and the gang to look up and see the three workers: mummified and cocooned to the cave ceiling by green slime. Sheriff Stone arrives and the workers are loaded into an ambulance. After the gang get another lecture about staying out of police business and disrupting tourism revenue, Fred steals one of the cocooned bodies and the gang take it to Professor Raffalo at Crystal Cove High School for analysis. Raffalo states that the man is alive and seems to be in stasis, though more tests will be needed. After asking whether Sheriff Stone approved of him working on the evidence, Fred awkwardly reassures him and hurries the gang out.

The gang head to Fruitmeir's, where store owner Franklin Fruitmeir promotes and sells his popular green dessert. Velma tries to hold Shaggy's hand but he panics when he thinks Scooby will see them, abruptly running back into the restaurant for more dessert with Scooby. This makes Daphne inquisitive, however Velma vehemently denies any romantic involvement with Shaggy and walks away. Daphne suggests that she and Fred go for a drive and comments on how nice a romantic gift like the locket would be, but is again disappointed when Fred is oblivious to her hints and talks about his next trap. That night, Professor Raffalo studies the cocooned workman in his lab and hears someone in the hallway. Discovering that it is only the janitor, he returns to work. Soon after, the janitor hears a scream: Professor Raffalo is cocooned to the ceiling in green slime.

Daphne, Velma, Shaggy, and Scooby arrive at K-Ghoul. Angel Dynamite takes them into the station lounge where the try to cheer up Fred, who blames himself for putting Professor Raffalo in danger. Velma reveals that she still has a sample of the green cocoon slime but is horrified to find Scooby eating it. To everyone's disgust, Shaggy also takes a bite -- though he quickly agrees with Scooby that the green slime is actually Fruitmeir's dessert. After turning up very little background information on Franklin Fruitmeir, the gang consider him a suspect and make Shaggy and Scooby dress up like girls so they can get jobs as waitresses at Fruitmeir's. When Shaggy asks why Velma and Daphne weren't sent in as waitresses, since they're already girls, Daphne explains "We refused", to Shaggy and Scooby's displeasure.

Franklin Fruitmeir leaves his two new waitresses to finish locking up the restaurant. The in-disguise Shaggy and Scooby quickly let the rest of the gang in to search for clues. Shaggy and Scooby find the Slime Mutant after opening a locked storage closet and are chased. Daphne wanders into the same closet and finds a hidden entrance to the Crystal Cove Caves.

Inside the caves again, the gang notice a fresh tunnel going under Crystal Cove Bank. Fred sets up a trap nearby, but it misses the Slime Mutant and drops a cage upon himself, Velma, Shaggy, and Scooby. The Slime Mutant sprays green Fruitmeir's slime into the cage to seal them in. Daphne unsuccessfully tries to escape the Slime Mutant by going back up into Fruitmeir's. The rest of the gang eat themselves out of the Fruitmeir's covered cage and arrive in time to save Daphne, cocooning the Slime Mutant to a wall using a hose spraying Fruitmeir's.

Daphne tries to thank Fred for saving her, but he tactlessly dismisses her and begins obsessing about why his trap didn't work. Sheriff Stone and Mayor Jones enter, upset that “the town’s latest tourist attraction” has been captured. The gang explain that Franklin Fruitmeir was going to use the disguise for a bank robbery, but are stunned when Fruitmeir himself walks in and announces that he was the one who called the Sheriff. Scooby unmasks the Slime Mutant to reveal Professor Raffalo, who admits his plan to rob the bank and frame Fruitmeir for it. As Raffalo is being led off by Deputy Bucky, Daphne interrupts to ask him about the locket she found, holding it out for him to see. Raffalo insists he's never seen it before, however Mayor Jones appears both surprised and upset by it, though his reaction goes unnoticed. Sheriff Stone begrudgingly admits that the gang helped by preventing the bank robbery, but quickly complains that they still cost the town revenue by unmasking another potential monster.

Later, the gang hangs out at K-Ghoul with Angel. Shaggy answers a phone call expecting a radio request, but the rest of the gang and Angel quickly gather around as a voice identifies himself as "Mr. E", who informs them that they are doomed for removing the locket from the cave. Before hanging up, Mr. E declares that they've uncovered the truth behind the Curse of Crystal Cove and that the real mystery is just beginning.

  • According to the show runners, despite the monster culprits shown Mystery Incorporated is not a continuation of Scooby-Doo, Where Are You! it is a complete reboot of the series.
  • The episode was originally aired as a sneak peek on April 5, 2010; it officially aired on July 12, 2010.
  • In standard continuity, the gang's surnames weren't revealed until more than ten years after their first appearance. In this series, they're already revealed in the opening theme song as credits.
  • Vincent Van Ghoul is a reference to the warlock of the same name from the TV series The 13 Ghosts of Scooby-Doo (with the likeness and voice of Vincent Price). In SDMI, he is a B-movie horror actor.
  • The title of the episode has a double-meaning. It could be referring to either the Slime Mutant or the Evil Entity who lives below Crystal Cove.


Cultural references

  • One of the tourists (voiced by Jeff Bennett) following Velma resembles Don Knotts. Knotts appeared as himself on the TV series The New Scooby-Doo Movies.
  • Professor Raffalo's physically resembles horror host, Mr. Lobo.
  • In the scene where the Slime Mutant corners Daphne by the door, the framing of their faces in the shot is an homage to Alien 3, where the Alien corners Ripley.


Animation mistakes and/or technical glitches

  • The first time Shaggy and Scooby are in their disguises, Shaggy's eyebrows are red like his wig. Also, when Scooby complains about his skirt, his eyebrows are yellow, while also flashing black.
  • When the gang awkwardly respond to Raffalo's not being paid well, their body movements don't completely match their voices.

Inconsistencies/continuity errors and/or goofs/oddities

  • None of the people in Velma's tour group are actually tourists. Either they all decided to move there afterwards or they all just happened to be new in town. It's also possible that they had just never taken it before. However, the two that talk are credited as tourists.
  • Before walking into Fruitmeir's, Daphne's carrying a purse around her arm which presumably contains Shaggy and Scooby's belongings, then when she enters, her handbag is gone and she's just holding said belongings.
  • Shaggy and Scooby had to disguise themselves as waitresses, simply because Daphne and Velma "refused." Why is Fred not considered?
  • A strange fact is that Franklin doesn't even know what his own dessert is made of, and the large storage room in the back of Fruitmeir's contains six barrels with radiation symbols on them, and many more smaller containers with that symbol. This is not explained.

Daphne: Just once it would be nice if someone thanked us for solving a mystery.
Fred: Good thing we're not in this to be liked.
(rest of the gang give irked looks)
Fred: Maybe that didn't come out quite right.

Colton Rogers: We're not saying find new friends, we're—
Paula Rogers: Yes we are. Find new friends.

Nan Blake: And what about this Fred Jones? Certainly there must be other boys.
Daphne: Not like Fred. He's, like, one of those geniuses that no one understands until they're dead.

Velma: Fred & Daphne are going to find out eventually.
Shaggy: I'm not worried about them. It's Scooby-Doo. He's my best friend.

Fred: Shaggy, start the car!
Shaggy: Wait! I thought you were going to talk to him?
Fred: He wasn't in a listening mood.
Velma: So you stole a body? Rockin'.

Angel Dynamite: Check it. If that dog mutates, I'm putting him down, dig?

Daphne: But if the cocoon is made of Fruitmeir's dessert...
Shaggy: That means if we capture the monster, we can have our own shop, and we can have an endless supply of Fruitmeir's dessert! Oh, boy.

Shaggy: Why are Scooby-Doo and I dressed like girls when Velma and Daphne are girls?
Scooby: Yeah. My skirt's too tight.
Daphne: Because Velma and I refused.

Daphne: Fred! You saved me!
Fred: Not right now, Daphne. I have to figure out why my trap didn't work.

Mayor Jones: Why is the town's latest tourist attraction cocooned to the wall?

Professor Raffalo: Oh, it was foolproof. Genius! That is, until--you--you--.
Sheriff Stone: Meddling.
Professor Raffalo: Meddling--yes! Meddling kids and your blasted dog ruined everything!
