Forbidden Forest

The Forbidden Forest is a place where the Bog Monster lives as seen in the episode "Bug a Boogie". As reported by Klump in the episode, he said that the place is actually full of grey quicksand.

In the episode, when DK and Diddy told Cranky about the practical joke they were playing on King K. Rool, Cranky scolds and tells them that the amulet they found was actually the evil amulet of the Bog Monster, so he sends them to the Forbidden Forest. After DK and Diddy left the cabin, what Cranky said is actually another practical joke Cranky made to teach them a lesson.

Trivia

 * The forest possibly may be inspired by the Forest Frenzy level from the Donkey Kong Country game.
