Boofy the Moose is the mascot in Sam's Fun City. Jeffy wanted to see Mickey Mouse on his birthday, he couldn't, since Sam's Fun City doesn't have Mickey Mouse, so the closest thing they had was this moose as their mascot. Since Jeffy realized he wasn't Mickey Mouse, he didn't like him, and instead, wanted to see Mickey Mouse, so Brooklyn T. Guy decided to make a Mickey Mouse costume and portray him. He first appeared in Jeffy's Birthday Trip!.
- He is actually Bullwinkle from Rocky and Bullwinkle.
