Goombas are brown mushroom creatures with eyes, eyebrows and two feet and no hands.
- They are one of the few enemies that have teeth.
- The boss of the World 4 Castle is a Mega Goomba.
- There is an abundance of goombas in World 1-4, which makes it very hard to complete if you need the Mini Mario power.
- Originally, a Goomba that came in contact with a Super Mushroom would turn into the Mega Goomba. This was removed to make the game easier.
