Mega Goomba

Mega Goombas are a sub-species of Goombas which appear in New Super Mario Bros. Wii. Mega Goombas are the largest species of Goombas and are twice as big as the Grand Goombas. Mega Goombas only appear in the World 1 Enemy Course where two of them appear trying to stop the player from saving the kidnapped Toad. Mega Goombas attack the same way regular Goombas do by walking into the player. When jumped on, they split into two Grand Goombas. It takes four Fireballs to defeat a Mega Goomba. Mega Goombas can't be frozen by iceballs from Ice Mario; they will break out instantly after being frozen.

Mega Goombas reappear in New Super Mario Bros. U. The act the same like in New Super Mario Bros. Wii, when they are jumped on they split in Grand Goombas. They are found in Soda Jungle with Gargantua Koopa Troopas. They can be defeated by Koopa Shells now.
