Goombas

Goombas are the primary enemies in the Mario universe, and have made significant appearances in IronYoshi1212's videos.

Characteristics
The Goombas are the primary foot-soldiers of Bowser's army. In the IronYoshi1212 video universe, Goombas are shown as Mario fanboys who chase after him so that they could get an autograph, much to Mario's dismay.

Trivia

 * The Goombas had distinctively high-pitched voices in some of the earlier videos, but in the newer ones, they sound like a less-obnoxious version of Toad.
