Crusty was an ordinary slice of bread who appeared as a pet to Junior. It challenged Cody's pet rock in a swim-off. As Crusty was thrown in the sink of water, the piece of crust came off. Junior ignored Joseph's warning and tried to get him out. This resulted to Crusty breaking apart and deforming. As Junior was crying over the loss, Joseph and Cody manage to recover Crusty's remains. The body of Crusty was thrown into the trash and he was never seen again.
