Mystery Mushroom

The Mystery Mushroom is a power-up that appears in Super Mario Maker. It resembles the sprite of a Super Mushroom from Super Mario Bros. with a question mark printed on its cap. If Mario touches one, he will transform into Costume Mario and take the form of one of various costumes, most of which are based on non-Mario Nintendo characters. The costumes can be unlocked by completing the 100 Mario Challenge mode; Alternatively, however, if the player scans certain amiibo, an 8-bit sprite of the amiibo's character 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 take the appearance of the 8-bit sprite himself. It has the same effect as an ordinary Super Mushroom as it grants Mario an extra hit point and he can break Brick Blocks, except it maintains or shrinks him down to (depending on his current state) Small Mario's size. Mystery Mushrooms can only be used in the Super Mario Bros. style of the game.
