When Squidward’s house gets destroyed, he reluctantly decides to take residence inside Patrick’s house. Soon, Squidward’s personality rubs onto Patrick, so Squidward takes on Patrick’s personality to make things even.

During a Krusty Krab anniversary celebration, SpongeBob, Patrick, Squidward, and Mr. Krabs accidentally get locked in the freezer.

Spongicus: Plankton has demolished the Chum Bucket! In its place, he has built a Roman coliseum and announces there will be a gladiator show, which means togas, chariots, and ferocious lionfish. And on top of all that, it’s free! No one in Bikini Bottom can resist, not even Mr. Krabs!

To avoid irritating Squidward, SpongeBob and Patrick dig a tunnel under their houses, much to Squidward’s annoyance.

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.

Plankton and Man Ray join forces and try to override the Krusty Krab.
