Ukiki is a dark brown monkey with a lighter shade around his face and ears. He has pink “blushes” on his cheeks, and blue eyes. His hands/legs have the same color shade as his face.
Ukiki only appears in Tall, Tall Mountain. He is the star of the second mission, "Mystery Of The Monkey Cage", where he will steal Mario’s Cap, in which the former must take it back from the michevious monkey.
- Ukiki is not a specific character, but rather part of a species with the same name that appears throughout the Mario series.
- Ukikis are also known (in other games) as "Grinders".
