He did go to jail in Lights, Camera, Pants! But it is unknown why. He is friends with Larry and is proabably friends whith the other fish who work out at Goo Lagoon. In the Bikini Bottom anchor toss the announcer fish said "First up, Don the Whale!" And he threw the anchor 210 yards He came in third place in the anchor toss Sandy being first, Larry being second Brown fish being fourth, and Spogebob being last.
