Fungi Forest, originally planned for Banjo-Kazooie, is the fifth level of Donkey Kong 64. The level revolves around the idea of changing day to night and vice versa, creating different challenges and unlocking and closing certain areas depending on what time of day it is. The landmarks of the level include Coocoo Clock, a giant Clock that alters the time of the level from day to night; the Mills and Barns, covering one area of the forest containing Golden Bananas; and the Giant Mushroom, a large building consisting of multiple stories.
