Mega Goomba (boss)

If you were looking for a different species of a huge Goomba, see here.

Mega Goombas are a sub-species of Goomba. A Mega Goomba is the boss of World 4 in New Super Mario Bros..

Before the battle, a seemingly regular Goomba transforms into a Mega Goomba. Mario must defeat this boss to aquire the key that provides access to World 5.

To defeat Mega Goomba, Mario can activate a switch, causing two platforms to appear. When Mario stands on the platform, it will elevate in the air. From there, Mario can either Wall Jump, Jump, or Ground Pound directly on top of the Mega Goomba. For the attack to be successful, Mario must Ground Pound the Goomba (unless he is Mega Mario). Mario can also go off to the side, simply wall jump, then ground pound on the Mega Goomba.

Once Mario hits the Mega Goomba three times, the Goomba will be defeated, and Mario can get the key to World 5.

The Mega Goomba also appears in New Super Mario Bros. Wii. However, the Mega Goombas in that game are nowhere near as gigantic as the one from New Super Mario Bros., but they are still bigger than Mario. When jumped on, it splits into two Grand Goombas.

Trivia

 * This Goomba originated in the very first previews of New Super Mario Bros. (or Super Mario Bros. DS, as it was called back then), in which it was a normal-level enemy Goomba until it came in contact with a Mega Mushroom. This made the normal Goomba grow to the enormous size of the current Mega Goomba. This new and innovative feature was taken out for unknown reasons, possibly due to the fact that the game would become extremely hard if certain enemies became large.
 * When the Mega Goomba grows, it makes a sound similar to Mario changing into Mega Mario, only it is somewhat more sinister-sounding.
 * Exactly 27 fireballs are needed to defeat the Mega Goomba.
