The werewolf's forest is a wooded area in which Werewolf Uniqua resides.
The forest is always dark. It is full of large rocks, steep hills, and trees without leaves. One of the trees (the grabbing tree) is larger than the others and can move its branches like arms.
The werewolf's forest has appeared in one episode of The Backyardigans: "Scared of You" from season two.
