S4·E4 Chimpanzee Choo-Choo

When a girl named Cynthia in Yaounde, Cameroon, asks for a toy train for her baby chimp to ride on, things get dodgy fast. Kimba, the chimp, takes off into the jungle where more chimps join him and cause trouble for the pursuing Superwings. In the end, Kimba and the train are saved, and Kimba is adopted by his new monkey family.
