After Shaggy finds a golden biscuit, the gang heads to the Scooby Snacks factory for a special tour. However, the tour is short and heavily monitored due to the owners' concerns. Then the gang finds another mystery in the form of a huge sludge monster made of Scooby Snack batter.
This episode includes examples of the following tropes:
- Attack of the Killer Whatever: The Monster of the Week is a factory worker who was mutated after getting too close and falling into the Scooby Snack batter. This creates a problem for Shaggy and Scooby, who have some run-ins with the monster thanks to following the smell or the tracks the creature leaves.
- Charlie and the Chocolate Parody: The gang wins a tour of the factory as a result of Shaggy winning a contest. Ernest Bailey wears a top hat like Willy Wonka, Scooby and Shaggy want to drink from a flowing river of food and are sucked up a pipe like Augustus Gloop, are nearly pulled into a fan like Charlie Bucket, are nearly fed to an incinerator like Veruca Salt, and become so full that become round and have to be rolled like Violet Beauregarde. A giant-size product package catches the monster like the one in the room that tempts Mike Teavee, and a glass elevator goes up into the air like in its sequel.
- Chekhov's Gun: Penelope Bailey, the creator's daughter, says she's allergic to Scooby Snack batter when Shaggy gushes over how cool it must be to work with snack food. This comes into play later when she claims to have been kidnapped and tied up by the monster. There was Scooby Snack batter all around her, but none on her, which made Velma suspicious that she had faked the attack to take suspicion off herself.
- Chekhov's Gunman: Trudy, the not-very-helpful new worker, turns out to be an industrial spy.
- Classy Cat-Burglar: Trudy, who has Catwoman like reflexes, and wears a dark suit and mask, while trying to steal the Scooby Snacks recipe.
- Company Cross References: Several to other Warner Bros.-owned IPs:
- A factory for "Looney Tunas", with a "shield" logo like Warner Bros.'.
- The monster resembles Clayface.
- And the monster falls into a packaging machine and comes out in an appropriate-sized box, similar to what once happened to Tom and Jerry in their (MGM produced) short, Cannery Rodent, and to Bugs Bunny's opponents Rocky and Muggsy in The Unmentionables.
- *Drool* Hello: The monster confronts the cat burglars as they're trying to open a safe. A few seconds before they look up to see it, a dribble of Scooby Snack batter falls on one of them.
- Evil Smells Bad: Inverted; the monster is covered in Scooby Snack batter, attracting Shaggy and Scooby like bloodhounds. Shaggy asks it at one point why it has to smell so nice.
- Marilyn Maneuver: When the sanitation chamber starts drying them, the girls have to hold down their skirts.
- Mythology Gag: This episode is similar to the A Pup Named Scooby-Doo episode Wanted: Chedder Alive.
- The gang solve a mystery surrounding the Scooby Snack factory.
- The Scooby Snack monster is similar to the Cheese Monster, the difference being the culprit here had noble intentions while the culprit behind the Cheese Monster wanted to drive the Scooby Snack factory out of business and steal the recipes.
- Speaking of which, the cashier Trudy, who's actually a spy sent to steal the Scooby Snack recipe briefly dresses up as the monster herself, much like the Cheese Monster culprit.
- And the culprit calls the gang "Pestering Kids" which is similar to the line "Pesky Kids" which the villains in the series usually called the gang after they were defeated.
- Playing Sick: When Daphne says they need to be the bait because of their keen noses for Scooby Snacks, Shaggy and Scooby claim to be catching colds to get out of it. It doesn't work.
- Prehensile Tail: Scooby uses his tail to undo the bolt on the Deadly Rotary Fan, dropping it down a shaft.
- Red Herring:
- Mr. Bailey has developed a habit of sleepwalking, making him a potential suspect. However, he's not actually the monster, just The Wonka of the factory who's low on sleep.
- Subverted in the case of our culprit. Penelope says she’s allergic to Scooby Snacks, so you’d think that she wouldn’t be the monster, since it would be totally illogical for her to cover herself in a costume made out of batter of the stuff. However, she is the monster- she’s wearing a hazmat suit to protect her from the batter.
- Well-Intentioned Extremist: Penelope's reason for being the monster was to protect the family business by scaring away thieves who were trying to steal the secret recipe.
- What Happened to the Mouse?: We never see what happened to the second thief in the opening. Mr. Meister mentions that the two thieves narrowly got away, but we never see more than the monster's attack on them.
- Wounded Gazelle Gambit: Penelope stages an attack on herself claiming she was kidnapped and tied up by the monster to throw off suspicion. However, Velma noticed something off with the claim when she realized there was no batter on Penelope, as if the monster knew she was allergic to it.
- Year's Supply Prize: As a reward for solving the case, Mr. Bailey gives the gang a lifetime supply of Scooby Snacks. Of course, with Shaggy and Scooby, a lifetime supply doesn't last very long.
