Moko has black fur and pink skin. She has black almond-shaped eyes with long lashes and wears a white sombrero and white mechanical dress and normal white boots. Mojo references say she has an invisible white cape related to Mojo's. She always seems to carry a fresh yellow unpeeled banana for reasons unkown. When she is not in performance criminal mode, she looks like a regular chimp, is naked and has pink feet a pink face, pink ears, pink hands and black eyes with eyelashes. She will always be 4 feet unless during criminal performance mode in which she wears some sort of foot wear.
