The Mega Mushroom is a very good power-up, rarely found but valued when found. It makes the user increase in size tenfold, allowing them to smash nearly everything, including foes, bricks, and pipes. It is mainly a large yellow mushroom that has red spots, and takes 2 seconds to pop out from a brick. The Mega Meter measures how much destruction you cause, and is measured by using yellow for parts to be filled, and green for filled parts. When the powerup shrinks Mario, he'll get however many 1-up mushrooms that the Mega Meter gives him, with a maximum of five. When the powerup is going to shrink soon, Mega Mario will flash green.
