Fungi Forest is the fifth level of Donkey Kong 64, which is accessible after the player returns the Gloomy Galleon Boss Key to K. Lumsy's prison, and has collected 50 Golden Bananas. It is, as the name states, full of mushrooms. The stage centers around a giant Cuckoo Clock. The Cuckoo Clock has the ability to change day into night and vice-versa. Many areas are only accessible during certain times of the day. Enemies are also affected by time. They often become more hostile when the sun goes down. Dogadon is fought in a rematch by Chunky Kong here.
This level also introduces blue Kong Switches, though a blue one does appear in the lobby of Gloomy Galleon. They can only be activated once the Kongs get the Super Simian Slam potion from Cranky Kong.
This area contains several barns and mills that house several creepy enemies. Inside these mills are mechanical tasks the Kongs will have to face to get their Golden Bananas. These tasks include walking on dimly lit planks, turning on a conveyor belt, killing Bats in the attic, and battling a giant spider with Tiny Kong only. Snide's H.Q. appears in this area, but is only accessible during the day.
Giant Mushroom Area
This area has a gigantic mushroom surrounded by water. Inside the fungus, the Kongs have to climb up the different floors of this mushroom to tackle bananas and bonus barrels. These floors also lead to terraces outside, which have many other tasks as well. Cranky's Lab can be found here.
