4x23 - SpongeBob SquarePants

In the battle for fast food supremacy, Plankton has decided to throw in the towel and start a new business selling trinkets and souvenir gifts. He even renames his store from The Chum Bucket to The Chumporium. But Mr. Krabs doesn't buy the change for a second. He's determined to prove that this is nothing more than one of Plankton's elaborate schemes aimed at stealing the Krabby Patty formula.
