You were walking through the mushroom kingdom and everything looked normal so you walked through the entire level although you noticed someone watching you but when you turned around they were gone so you continued walking until you heard a noise coming from behind you and when you turned around Turn around you saw an anthropomorphic hedgehog dressed as Mario on the ground while an angry mushroom power up bounced off his butt making it grow uncontrollably

Hey dude, could you help me with this mushroom that won't let me get up and my butt won't stop growing?
