Mario's doctor heard about the "Magic Mushrooms" which make Mario grow to twice his normal size and let him break bricks. Fearing for Mario's health, he orders Mario to avoid those nasty powerups.
This run aims to complete as many exits as possible without collecting any permanent powerups, including Mushrooms, Fire flowers, Feathers, Switch Palace blocks. Unable to fly, Mario is forced to confront most obstacles and overcome them in unique ways. Riding Yoshi is also banned. 86 out of the total 96 exits are completed.
