Mystery Mushroom

The Mystery Mushroom is a mushroom that gives a costume to Mario, and they are only avaliable in the Super Mario Bros theme. Mystery Mushrooms don't grant Mario any new abilitys, but it does change the look, and some times adds new sounds for jumping, running, winning, and falling in a pit. The costumes also add a new use to the using up on the joystick and d-pad, it's make a character do a pose that can sometimes have a sound. There are currently more than a hunderd amiibo costumes, including Sonic the Hedgehog, Pac-Man, Duck Hunt Dog, Donkey Kong Jr, and Mario, Luigi. You can unlock them in the 100 Mario Challenge, in some Event Courses, and you can scan a amiibo on the Wii U game pad. There's also a special amiibo costume that you can't unlock, and you need to get the 30th Anniversary Super Mario Brothers amiibo to unlock it, and it grants the ability to through smash bricks and ice,change the appearance of Mario, and most of the objects in the Super Mario Brothers theme. The amiibo is available in the modern colours, and the classic colours. There is also a Weird Mushroom in Super Mario Maker that makes Mario have a longer jump and worker traction, like Luigi in most games he appears in.
