Loop Loop River

Loop Loop River is the fifth level of World 3 in the game Paper Mario: Sticker Star. As the name implies, this level takes place in a looping poison river than runs through the inside of a cavern, and contains several plains along the borders of the river.

Layout
Mario starts the level near the river, where a Heart Block can be found. There are several Snifits walking in the poison, with only their heads visible. There are a few broken, wooden bridges and elevated plains here. Mario must head right until he finds a door leading to a cavern. Upon entering this door, Mario is taken inside the cavern, where a wooden bridge can be used to cross the poisonous river, which runs through the cavern.

A Boomerang Bro can be found in the other side of the river, as well as a door. This door takes Mario to an open area with a single Ninji and a small tree. Mario must hit this tree with his hammer to cause the only leaf of the tree to fall off, allowing him to use it as a moving platform across the poison river. Then Mario reaches the inside of the cavern through the left door, he must jump from the leaf, and land on platform.

Mario must then find a door located on a platform with two ? Blocks and a Brick Block. By heading through this door, Mario finds the Wiggler Segment, who is sleeping on the ledge of the platform, covered in small Butterflies. When Mario approaches the segment, it wakes up and engages a battle with Mario. After defeating the segment, Kersti yells at it, causing it to feel bad for its behavior and join Mario. The Comet Piece can be found ahead, in a platform.

After Gooper Blooper's defeat, the river will no longer be poisoned, and Shy Guys appear in the place of some Snifits.

Secret exit
When Mario is riding the leaf through the poisonous river, he must ride it all the way to the beginning area, and jump to an elevated plain with a Piranha Plant. There, he must use one of three Hidden Blocks floating high above the poisonous river to jump to a platform on the other side, where he can find a door. By heading through this door, Mario is taken to a platform inside the cavern where the secret Comet Piece is found.

Secret Door
In the area with the Boomerang Bro, the Secret Door location is to the right of it. The door leads to a secret room with the Pillow thing.
