Andre (dinosaur)

From Muppet Wiki

Andre is the boorish dinosaur biker gang leader, temporarily replaced by Robbie in the second season Dinosaurs episode "Leader of the Pack." When Andre disappears after a drinking binge, it's assumed that Robbie ate him. However, Andre merely developed amnesia, was adopted by beavers, built a couple of dams, remembered who he was, and then ate his new parents.
