Donkey Kong Jr.
Donkey Kong Jr. (voiced by Frank Welker) is sad to find that his father has run away from Mario and the circus. He befriends a greaser nicknamed "Bones" (voiced by Bart Braverman) who has a motorcycle and offers to help Junior by finding his dad together. Donkey Kong Jr's catchphrase is "Monkey muscle!", which he tells to himself and Bones to inspire self-confidence. Bones often serves as the voice of reason when Donkey Kong Jr. bites off more than he can chew.
