Green banana
A Green Banana is an item from the Donkey Kong franchise. They resemble unripened bananas also known as Guineos.
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 are not fast enough, any uncollected Green Bananas disappear.
Through the use of the "MERRY" code, which gives 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.
