Whammino Mountain is the fifth level of World 1 in Paper Mario: Sticker Star. It is known as World 1-5.
Unlike all of the previous levels, Whammino Mountain has a little amount of rock to walk on, instead of grass. Though it's main colors are still green and brown.
After finding the Secret Exit back in Water's Edge Way, Mario ends up high in the mountains to continue his search for the Royal Stickers. Mario, at one point, encounters a Lakitu that drops many Spinys. Fortunately, there is a Starman that allows Mario to run through each of them with ease. Mario eventually has to Paperize a White Gate in order to continue with his quest. After fighting many enemies later, Mario manages to peel a Toad that runs a Sticker Shop just ahead. After leaving the shop, Mario triggers a Rube Goldberg machine that results in a clear path to the Comet Piece.
