Forever Forest is a short distance to the east of Toad Town in Paper Mario. Because of some magic, the forest can only be traversed by following the path in front of something different. These differences can be anything from what flowers do on bushes to glowing eyes in a tree. Oaklie and a Bub-ulb are the only sentient, living residents of the woods. At the end of the woods is Boo's Mansion, where Lady Bow and her servants live. Continuing past the mansion, one will find Gusty Gulch, home of Tubba Blubba's Castle and a small Boo village.
Inside the forest is a Magical Seed, anHP Plus Badge, and anFP Plus Badge. After completing the Chapter, you can fight Jr. Troopa who obtains bat-like wings and retains his spike.
