Walking Trees are enemies that appear in Haunted Valley. They come in two versions but there aren't any differences between them.
As the name suggests these enemies are alive trees. They have brown tree barks from which leak yellow substance. Their upper branches have leaves and bird bones. Also their eyes emit glow - green in first version and red in second. They not fast in movement, however their attacks can be dangerous. They have two methods of attacking. The first is to swipe the player with their "arms" that are actually their branches. The second is much more dangerous as they will exhale poisonus gases from thei mouths and that does significant amount of damage.
