Humphrey's first speaking role was in "Me Adam, You Jake", where he, Hazel Peacock, and Laura Owl tried out for the school play, Jungle Guy. All of them practiced their Jungle Guy yells, but Humphrey complained about the yell being really complicated to master. Hazel shot back at him, claiming she had a simple time taking on the yell. She demonstrated and Humphrey applauded and congratulated her, alongside Laura.
- His name is a reference to the forgotten Disney character, Humphrey the Bear.
