In Brief: Mermaidman leaves his belt behind and SpongeBob gets hold of it.

Story: Mermaidman and Barnacleboy come to the Krusty Krab to eat. Mermaidman orders a double krabby patty and coral bits for himself and a silly meal for Barnacleboy. While eating their meal SpongeBob sees them and runs to get their autograph. They run out of the Krusty Krab to avoid him but Mermaidman leaves his belt. SpongeBob finds it and puts it on. He starts to press buttons and finds the small ray. SpongeBob starts to shrink everything in the Krusty Krab kitchen. Squidward comes in the kitchen and wants to know why everything is so tiny. He sees the belt and threatens to tell Mermaidman that SpongeBob stole the belt. Squidward picks up the phone and begins to call Mermaidman. SpongeBob shrinks him before he gets the chance. Squidward demands to be unshrunk, but SpongeBob can't find the right button.

SpongeBob runs to Patrick's house to see if he knows what to do. Patrick thinks Squidward is an action figure and starts to play with him. SpongeBob explains to Patrick that he accidently shrunk Squidward. Patrick tells SpongeBob that he had it set to M for mini, when it should be set to W for Wumbo. SpongeBob presses the button again, but this time shrinks Patrick also. SpongeBob puts Patrick and Squidward in a jar, until he can figure out what to do. Sandy comes up from behind him and surprises SpongeBob causing him to accidently shrink Sandy also. Next, SpongeBob shrinks Larry, Mrs. Puff, and continues until the whole town is small.

SpongeBob stuffs the whole town into his jar, and Squidward demands that he tells Mermaidman what he did. SpongeBob says he can't do that because Mermaidman will be so disappointed. From inside the jar Mermaidman tells SpongeBob to set it to Wumbo. Everybody jumps out of the jar and leaps into SpongeBob's body. They start to kick and punch all his organs including his brain, lungs, and bladder.

Suddenly, SpongeBob gets an idea. Since he can't make everybody big, he decides to make the city small. He shrinks all the buildings and then finally shrinks himself. Everybody seems very happy with this idea and they all cheer. A bus pulls up to the shrunken Bikini Bottom and Plankton gets off, whose now giant compared to how small the town is. He looks down in shock at the tiny buildings.

Barnacleboy: It's not for the toy, I just...I've gotta fit in the tights, y'know?

Patrick: Oh, boy! A Squidward action figure! Let me play with it!

Mermaidman: Your mother's right, son. Mermaidman will understand.

Barnacleboy: You're Mermaidman, you old coot!

Mermaidman: Oh yeah.

SpongeBob: Mermaidman? I'm so sorry, it's just that I'm such a big fan, and your belt, and...

Mermaidman: Oh, don't worry son. I understand. Why, I remember back when I first used the belt, the year was nineteen o eleventeen twelve, why I believe the president...

All: Just tell him how to unshrink us!
