The Tree Forts (formerly known as the Tree Fort), was the party room during the Adventure Party. It was for members only. It looked pretty much identical to the Treetop Fort from the Medieval Parties and had a free item, the Tropical Bird. A feature of the room is a tropical plant that grows when penguins "feed" it snowballs. It keeps getting bigger until at the end it burps and returns to its original size. The Tree Forts returned in the Island Adventure Party 2010, almost identical to its previous appearance. This time the free item was the Marooned Outfit.
