Fungi Forest

Fungi Forest is the fifth level in Donkey Kong 64. 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 world also introduces blue Kong Switches. They can only be activated once the Kongs get the Super Simian Slam potion from Cranky Kong.

Although this is the second level that Candy's Music Shop does not appear in (the first being Jungle Japes it didn't appear in), her headphones can be found at various locations in this level.

Entry to this level requires 50 Golden Bananas.

Mill Area
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 Flip-Flaps in the attic, and battling a giant spider with Tiny Kong only. Snide's HQ 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.

Big Tree Area
This area has a humongus redwood tree, inside of which sleeps an owl that Diddy Kong must race (only during the night). Around the tree is a rabbit house, a smaller tree, and Lanky Kong's Kasplat. Cranky's Lab can be found here.

Garden Area
This area has a tomato patch with several Killer Tomato enemies surrounding an apple with a worm in it. Tiny Kong can plant seed in a hole which grows a giant living beanstalk. Funky's Armory can be found here.

Trivia

 * This level was originally going to be in Banjo-Kazooie (where it was called "Fungus Forest"), but was instead added to Donkey Kong 64. A picture of Fungus Forest can be seen in Banjo's house.
 * The boss battle against Dogadon in this level takes place in a lava arena, although the real level does not have any lava in it.
