Old Bananas (aka. O.B.) is a famous orangutan who starred in a sitcom entitled "That's My Orangutan", until pet watch-dog groups steered TV networks away from doing any imitate-able behavior. The show is currently running again on Planet of Pets Channel. Pepper has idolized him since she was little, and strove to get his approval. He appeared in "Lotsa Luck", voiced by Sam Vincent.
Old Bananas is a skilled comedian and a famous animal star.
Initially he appears as a grumpy ape, who won't even crack a smile. However, this is later revealed to be an act, to prepare Pepper for show business. He is in reality a supportive individual and admires Pepper for her skills.
