"A Place for Pets": Mr. Krabs allows pets in the Krusty Krab, although a health violation forces him to choose between restricting the restaurant to either people or pets. When he favors pets, much to SpongeBob's delight and Squidward's dismay, the other customers collectively refuse to eat at the Chum Bucket and begin disguising themselves as pets to get back in.

Meanwhile, Plankton attempts to find Santa's naughty and nice list and transfer his name to the nice list.
