Mushroom Ball

Mushroom Balls are items found in Mario & Luigi: Bowser's Inside Story; they are balls in the form of red mushrooms. There are 16 total, each holding their own special prize if Mario and Luigi hands them to a yellow Toad with a mustache. They are found around at the Toad Town Mall in hidden blocks and by spin drilling underground.
