Kongo Bongo is the setting of the french Donkey Kong Country TV show.
Other characters are mentioned, like the "very cute lizard" mentioned in "From Zero to Hero" and Bluster's mother, though the latter likely lives elsewhere.

Inside Kongo Bongo lies the mysterious Crystal Coconut. As future ruler, Donkey Kong (the one who found it) is to protect it at all costs from King K. Rool and his minions, the Kremlings.
