Donkey Kong's Banana Hoard is a special cave near Donkey Kong's jungle home where he stores his countless Bananas. King K. Rool stole the Bananas for unknown reasons in Donkey Kong Country. Donkey and Diddy Kong made it their mission to retrieve them one by one, and eventually succeeded.
Only normal, edible Bananas are stored in this cave. The Golden Bananas from Donkey Kong 64 were stored in an undisclosed location.
The Banana Hoard once again appears in Super Smash Bros. Brawl story mode, the Subspace Emissary. Bowser (likely) sent out a Hammer Bro and a Goomba to steal them. Donkey Kong started to chase them and knocked out a Goomba and two Koopa Troppas. When he finally got out of the jungle, he still couldn't catch them as they drived to fast and was too far from him. The Gommba jumped to two Bill Blasters with fired three Bullet Bills toward DK. Diddy Kong the jumpes out of the jungle and jused his Peanut Popgun to stop them.
