Jungle Japes

Jungle Japes is the first level in the game Donkey Kong 64. Since this is the first adventure stage of the game, it's where the player learns to do many things, including collecting bananas and transforming into Rambi the Rhinoceros. It is located in Donkey Kong Island and requires one Golden Banana (found near the entrance itself) to enter. Diddy Kong is held captive here in a mountain prison.

Jungle Japes, as the name suggests, has many jungle areas, filled with climbable trees and collectibles. There are many cliffs that the Kongs climb, one of which has a mine area. The jungle also has many gloomy tunnels full of swinging light bulbs and Gnawties. One of these caves leads to an area with a heavy storm where the Kongs slam switches to reveal Bananas. Another cave leads to the secret area which requires Tiny Kong to shoot the switches with her Feather Bow to open the gate, and that area has a few objects based upon the later level Fungi Forest. The boss of this stage is Army Dillo, which requires 60 regular Bananas both from Donkey Kong and Diddy Kong to enter.
