Mega Goombas are enemies that appear in New Super Mario Bros. Wii. They are a bigger sub-species of Grand Goombas. They only appear in World 1's Enemy Course. Two Mega Goombas are one of the many enemies that will appear randomly in this Enemy Course (the others being four Grand Goombas and eight Goombas). Mega Goombas are twice as big as Grand Goombas, therefore they split into two Grand Goombas when stomped (jumped) on. Even though they are two times bigger than Grand Goombas and four times bigger than Goombas, they behave just like regular Goombas and Grand Goombas. All these enemies do is walk around the arena. Mega Goombas can either be defeated by splitting them into two Grand Goombas, then into Goombas and stomping on those Goombas, by firing four Fireballs from Fire Mario (or Fire Luigi, Blue Toad, or Yellow Toad) using a Fire Flower or by running into them while under the effects of Starman. However, if one character touches a Mega Goomba, they will lose a form or die at small form.
