Mystery Mushroom

The Mystery Mushroom is a power-up that appears in Super Mario Maker, where they become available for use in the game's level editor if the player scans a certain amiibo. It resembles the sprite of a Super Mushroom from Super Mario Bros. with a question mark printed on its cap. After scanning an amiibo, an 8-bit sprite of the amiibo's character, known as a Mystery Suit, will appear on-screen, which can then be placed inside a ? Block, turning it into a Mystery Mushroom. Upon touching one while playing, Mario will transform into Costume Mario, taking the appearance of the 8-bit sprite himself. It has the same effect as an ordinary Super Mushroom, except it maintains or shrinks Mario down to (depending on Mario's current state) Small Mario's size. Mystery Mushrooms can only be used in the Super Mario Bros. style of the game.
