Galoomba

Galoombas (named "Goombas" prior to Super Mario 3D World) are somewhat rare enemies. While some Galoombas are stationed in certain locations as guards, others are dropped from the sky in droves like Para-Goombas. They either parachute from above or float down in bubbles (which burst upon coming into contact with any object), or can even appear with wings to hop around. They later reappear in Super Mario 3D World, where the translators gave them the name "Galoomba" to distinguish them from regular Goombas in the Wii U title.

Super Mario World
In this game, Galoombas are referred to as "Goombas" due to a translating error, despite acting differently. Although these creatures walk in straight paths to attack, like regular Goombas, these new baddies do not resemble the older ones. Goombas do not have mushroom-shaped heads, but spherical ones. They also lack a stem: the Goomba's two feet are attached directly to the bottom of the head. As such, they resemble angry chestnuts more than scowling mushrooms.

Goombas cannot be defeated in a single jump, as doing so flips them over and immobilizes them. In this state, they can be picked up and thrown at other enemies, like with Koopa Troopas. Running into them or jumping on them when flipped causes them to be kicked around. After a few seconds they right themselves, which damages Mario if he is carrying one. They can automatically be defeated with a Spin Jump, or with a fireball or an attack from Yoshi; an attack with the cape causes them to be flipped over as well.

There are two variants of Goombas in the original game. Para-Goombas are Goombas which utilize parachutes instead of being Goombas with wings. Winged Goombas also appear, and can only hop on the ground instead of fly. Like Paragoombas, Winged Goombas' wings are clipped after one jump, leaving them rendered as a normal enemy. However, just as the Goomba counterparts in Super Mario World, stomping on them after their wings are gone just renders them helpless for a few moments, allowing the player to throw them at other enemies. This variation later appeared in Mario Clash.

In the Super Mario World Game Boy Advance remake, Super Mario World: Super Mario Advance 2, after the player beats the Special World and finds all of the exits, the Goombas are colored yellow and wear sunglasses.

Super Mario 3D World
Galoombas reappear in Super Mario 3D World after 8 years of absence alongside regular Goombas and a bigger variation named Big Galoomba. Like normal Goombas in 3D Mario games, they attempt to chase after the player upon seeing them. Additionally, like in Super Mario World, Galoombas cannot be defeated with one jump, as that causes them to be flipped over, though unlike Super Mario World a second jump defeats them. A Ground Pound can also be used to defeat them in one hit. Additionally, Galoombas cannot be kicked around, as running into them while immobilized also causes them to be defeated.

Super Mario World (television series)
Galoombas (referred to as goombas) made brief appearances in two Super Mario World episodes- The Wheel Thing and The Yoshi Shuffle. Winged galoombas appeared in Fire Sale. They were also briefly mentioned in A Little Learning.

Mario Party 3
Flying Galoombas appear as an obstacle during the mini-game Ridiculous Relay. The single player must dodge both them and Banzai Bills in their hand glider, and reach the finish line before the other thee players do.

Mario Party Advance
The Galoomba species are also seen in Mario Party Advance for the Game Boy Advance. There are two of them in the game, named Goombob and Goombetty.

Trivia
