Elroy is a Chihuahua owned by Rich. He is pure white and wears a Blue Polka Dot Ribbon on his chest. He is mean like Casey. If your dog comes towards Elroy, a different theme will play and the game will say that your dog does not like Elroy very much. Rich often brags about Elroy, saying that he did a backflip when told to sit or that he repeated the songs Rich played on the Keyboard.
