Wally is Denver's closest friend and the deuteragonist of Denver, The Last Dinosaur. He cares about various animals and has 6 pets: his puppy, Rocky, 3 cats, his rabbit, Ears, and a parrot. He especially cares about Denver and he and his friends do everything they can to keep him out of sight, since he worries that someone will want to take him away, like Morton Fizzback or Dr. Funt. Wally is Heather's younger brother. He is also voiced by Adam Carl.
