The Evil Forest (also known as the Evil Dark Forest) is a location in Adventure Time. The forest first appears in the episode "Tree Trunks." It is home to a variety of creatures, most of which seem to be hostile. The Crystal Gem Apple lies deep inside the forest. It is not known if there are any other items of value in the forest, which Finn, Jake, and Tree Trunks attempt to find in the same episode. The forest consists of dark, twisted trees, most of which have expressions of horror, pain or anger on their trunks.
