There are five main colors of the bananas with each color representing a Kong: yellow for Donkey Kong, red for Diddy Kong, purple for Tiny Kong, blue for Lanky Kong, and green for Chunky Kong. There are a total of 100 Bananas for each Kong per level that contains them. Collecting 75 bananas in a level results in a Banana Medal which 15 of them is needed to play Cranky Kong's Jetpac game.
However, the main purpose of the bananas is to feed them to Scoff to have him pound the platform to have Troff unlock the boss door. All the Kongs can contribute by feeding Scroff the bananas to open the boss door. When the Kongs collect 100 bananas, a special sound is heard when they do. The bananas may also come in bunchs of 5.
