Donkey Kong 64/Fridge

Fridge Logic

 * Why do the boss keys, designed by Kremlins, have the DK insignia on them?
 * K. Lumsy's island is floating in the water. How does his stomping send tremors trough the ground and break boulders? Or open a door on a floating island?
 * No, no, no. K. Lumsy doesn't open the door on the floating island - he breaks the boulder covering the cannon leading to said island. Still doesn't explain why it works though.
