By the end of the game, if you're going for full completion, you'll have collected 201
Golden Bananas, 9 Boss Keys, 4000 regular
Bananas (every time you
get 75 regular
Bananas with a Kong, you
get yet another collectable called a Banana Medal, by the way), 20 Faeries, 10 Battle Crowns, a Rare Coin, and a Nintendo Coin.
DK is cut off from most of the Island by sentries K. Rool has sent to impede DK's progress, and the only way to
get rid of them is by appeasing them with your
Golden Banana collection (
Golden Bananas are the Stars or Jiggies of DK64, if you will).
