Patrick's.
They take the Piece of the Pie to the authorities. During the time while the Detectives interrogate the Pie, Patrick and Spongebob look around Conch Street for clues. Spongebob tells Patrick to look for crumbs. Patrick soon finds a trail of crumbs leading to the Conch Street bus stop. They follow it back, and it's not in the front yard of the pineapple. It's at the end of the street. Patrick says, "Maybe he just put it in his pocket during the robbery, and he took the bus." Spongebob says, "Pat, your a genius! Come on, let's go!"
