Jumanji: The Animated Series

Peter and Judy find Alan in a bizarre costume near some circular ruins, a victim of total amnesia. To get him to remember, they take an old steamboat upriver from the ruins where they are captured by Manjis in Alan masks. When Alan claims that he's not Alan Parrish, but actually the creator of Jumanji, the Manjis intend to sacrifice him. But Peter and Judy come to the rescue and discover the statue contains a concealed hypnotic device responsible for Alan's illusions.
