Back it up

A street signpost displays the words "COCK" and "ANAL" on intersecting signs against a blue, underwater background. The scene cuts to a black screen, then shows Squidward and SpongeBob in a car, with Squidward looking annoyed and SpongeBob smiling. SpongeBob, now wearing a chef's hat, looks surprised while holding a bottle. He then transforms into a large, round, yellow cube with a face, standing over a plate of food while Squidward looks up at him from below.
