Green banana
A Green Banana is an item from the Donkey Kong franchise.
History
Donkey Kong Country 3: Dixie Kong's Double Trouble!
Green Bananas first appear in Donkey Kong Country 3: Dixie Kong's Double Trouble!, where they are found in certain Bonus Areas. In these Bonus Areas, the object is for Dixie and Kiddy Kong to collect fifteen of them within a time-limit. If they succeed, they are awarded with a Bonus Coin. The catch here is that only one Green Banana appears at a time, and they appear in random spots, forcing the Kongs into scrambling to collect them. If the Kongs aren't fast enough, any uncollected Green Bananas disappear.
Through the use of a code, which can give the Bonus Areas of the game a Christmas theme, the Green Bananas are replaced with presents, which serve the same purpose.
Donkey Kong 64
Green Bananas later reappear in Donkey Kong 64 as collectibles for Chunky Kong.
