Banana Birds (scientific name: Bananus Goldus Flutterus) are birds that are, strangely, made out of partially peeled bananas. They play a very important part in the game Donkey Kong Country 3: Dixie Kong's Double Trouble!, where a few are bought from Brothers Bear and won from Swanky Kong and Funky Kong, among others. They are found in secret caves in the Northern Kremisphere, where a "Simon Says" like memory game with four colored crystals was played to obtain a bird and free it from its crystal prison.
All except four could be found using Funky's ordinary rental vehicles, but to get 103%, Kiddy and Dixie Kong had to obtain all the DK Coins from Koin in each level, give them to Funky, and obtain the Gyrocopter. Using this new vehicle, they were able to access the last three caves and give all the Banana Birds to Wrinkly Kong. When Kiddy and Dixie visited Wrinkly after collecting all the Birds, the little creatures grabbed the two and carried them to their mother, a big Banana Bird living in the clouds. It turns out that Baron K. Roolenstein had cursed them, causing the babies to be trapped in crystal and the mother in a huge stone contraption. But when they were all reunited, their singing broke the spell. The mother then chased K. Rool down as he tried to escape on his Hover Craft, but she soon overtook him and dropped a huge egg upon him, fulfilling the game's true ending.
