Big Galoombas (also called Mega Galoombas or Grand Galoombas) are rare enemies that first appear in Super Mario 3D World. They are the larger versions of Galoombas and can be defeated by jumping on them twice, the same way that regular sized Galoombas can be defeated. Big Galoombas attack the same way Galoombas do, by bumping into the player, and usually come in groups of two or more. They only appear in the levels Big Galoomba Blockade and Gargantuan Grotto. The Enemy Blockade of World 2 consists of the player having to fight three Big Galoombas on a land patch surrounded by lava. In Gargantuan Grotto, they appear alongside Goomba Towers, Bloopers, and other enemies.
Big Galoombas also appear in Super Mario Maker, Super Mario Maker for Nintendo 3DS and Super Mario Maker 2 where they can be produced by applying a Super Mushroom to a Galoomba in the Super Mario World style or the Super Mario 3D World style. In these games, their behavior is identical to a standard Galoomba.
