Done in the style of the classic noir mystery films, the short begins when SpongeBob is wondering why he's called GumShoe SquarePants, then he steps on a piece of gum, thus realizing why he is called that way. He inspects it and chews it. After that, he accidentally smashes Plankton. SpongeBob does not want to be known as “PlanktonShoe SquarePants," so he decides to smear Plankton off of his shoe, then walks away, claiming that he has another mystery to solve: where he is right now.
