IGN - Stickers on the wall. Stickers on the doormat. Stickers in the tree, behind the building and in a Question Block. Stickers crumpled up on the ground, in a Toad’s dresser and in that hidden corner. Stickers from fallen enemies and in secret stores. Mario’s a sticker, the princess is a sticker, your sidekick is a sticker. All the Toads, Goombas and Koopas are stickers too.
