Plankton!: SpongeBob falls victim to a scheme by the evil Plankton, Mr. Krabs’ minuscule arch-rival with the Napoleon complex. Plankton hides out in SpongeBob’s head and takes control of his brain. SpongeBob finds he must fight his own body to prevent himself from handing over the secret Krabby Patty recipe to Plankton.

In order to beat Mr. Krabs at arm-wrestling, Plankton brings the glove on top of the Chum Bucket to life. It begins running rampant around town, so Plankton teams up with SpongeBob and Hans, a live-action hand seen during the show’s theme song, to stop the glove.

SpongeBob and Patrick find Sandy’s box of sports equipment, but do not know how to play the sports. As revenge, Squidward teaches them incorrect and painful ways to play. Sandy eventually finds out, and beats Squidward at his own game.

Mr. Krabs sends SpongeBob into the Krusty Krab’s underground lost-and-found to find a child’s missing toy. There, he meets a group of old people who have gotten lost years ago.
