Pile Driver Micro-Goomba

Pile Driver Micro-Goombas are a special variety of Mini Goomba that hide in Brick Blocks. They appear in Super Mario Bros. 3 and its reissues.

Super Mario Bros. 3
Pile Driver Micro-Goombas first appear in World 2-1, the first area of Desert Land, and are a staple enemy in the various desert and sky levels throughout the rest of Super Mario Bros. 3. They are disguised as grounded Brick Blocks that can be distinguished by the fact that they do not glisten (except in Super Mario All-Stars, which gave them a light-colored outline instead, but this was changed back in Super Mario Advance 4: Super Mario Bros. 3). When Mario or Luigi approaches their Brick Block, the Pile Driver Micro-Goomba moves slightly to show a pair of feet underneath the Brick Block, then jumps high in the air and attempts to land on the plumber to damage him. These enemies are resistant to fireballs and can be defeated by stomping, hitting it with a Raccoon tail, or by tossing a Koopa Shell at it.

The Adventures of Super Mario Bros. 3
Although no Pile Driver Micro-Goombas appear, a group of Pile Driver Micro-Goomba-like blocks make one small appearance in The Adventures of Super Mario Bros. 3, in the episode "A Toadally Magical Adventure". Although they have similar characteristics and looks as Pile Driver Micro-Goombas, they are real Brick Blocks brought to life, and are only referred to "blocks". These blocks were created by Toad's Pipe Creatures after they rebelled against him.

NES Remix 2
In NES Remix 2, Pile Driver Micro-Goombas, simply referred to as Mini Goombas, are featured as a Super Mario Bros. 3 challenge, where the player has to defeat three of them in World 2-1 within twenty seconds.

Ultimate NES Remix
In Ultimate NES Remix, these Mini Goombas have the same appearance and role they had in NES Remix 2.
