Her only appearance is in the episode "Meet the Beat-Alls".
Moko is a parody of performance musician Yoko Ono, who is often attributed as the leading cause of the Beatles' dissolution as a band after she became romantically involved with guitarist John Lennon.
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 white boots. Mojo references say she has an invisible white cape related to Mojo's. When she is not in performance criminal mode, she looks like a regular chimp, which she will always be unless during criminal performance mode.
