In the Krusty Krab, a woman fish steps over and files a complaint about something wrong with her Krabby Patty. It has a sea urchin in it and Squidward is very freaked out by this. He tries to smash it with the register, but ends up getting the urchin on his nose. He tries to smash the urchin again, but falls out of the register, with the urchin still on his nose. SpongeBob takes the urchin off his nose and takes it to his workplace, but the urchin bites him and falls down, turning the grill's heat to very hot, without SpongeBob noticing. As SpongeBob cooks, he gets hotter and hotter and sweatier and sweatier. He notices his mistake too late and is shrunk down smaller than his spatula.
SpongeBob gets up and climbs onto the counter. He says "It's huge!" to everything he sees. He then skates on the grill using butter, but the grill burns out and turns off. SpongeBob goes down to the bottom of the grill to investigate.
He finds the urchin in a mousetrap. He sets it free, and in return, it chases SpongeBob. The two run up and SpongeBob activates a soda machine. They then are washed into a drain, but SpongeBob is able to escape, while the urchin falls down, leaving his fate unknown.
Squidward then rings the bell for a Krabby Patty. He carries one out down into the seating area. Squidward thinks SpongeBob is an urchin trying to steal a Krabby Patty, and tries to smash it. Mr. Krabs picks SpongeBob and the patty up, and flicks SpongeBob to the Chum Bucket, mistaking him for Plankton. He lands on Plankton, who wonders why SpongeBob is so small, but then measures both him and SpongeBob and says "I am a towering half a millimeter taller than you! I win!" SpongeBob then lets some measuring tape wrap Plankton. He then touches it, slicing Plankton into pieces.
SpongeBob is kicked out and lands on the Krusty Krab window. A kid picks him up, thinking he's an action figure. He shows the "action figure" to his friends, and they fight over it. SpongeBob runs away, until he jumps into Squidward's shirt pocket. SpongeBob is now safe, and Mr. Krabs says the kids need to get their parents' money to get the "action figure." The kids run the customers out of the restaurant.
Mr. Krabs then realizes the "action figure" is SpongeBob after Squidward points out that they do not sell action figures. He then says that now that SpongeBob is so small, he only earns a penny a year. He is also now a personal hygienist. After doing stuff such as mowing a guy's back, and doing something in another guy's toenails, SpongeBob takes a break and lays on the sink.
An angry Squidward uses SpongeBob to clean the dishes, mistaking him for soap. Squidward then drops SpongeBob into the soapy water, growing him so big that he takes up the entire Krusty Krab. Mr. Krabs, in SpongeBob's hand, yells for Squidward to call the fire department. The giant SpongeBob says "No need to call them, Mr. Krabs," then walks there while using the restaurant as new clothes.
