SpongeBob SquarePants stands inside a barrel labeled "MUSTARD" in the Krusty Krab kitchen, smiling and holding a spatula, while Mr. Krabs watches from the side; SpongeBob then becomes completely covered in mustard, his expression shifting to smug as he stands in the barrel, before the mustard erupts and he disappears, leaving only his hands and a spatula visible above the mustard.
