Gloomba

Gloombas: Grumpy, blue Goombas. A Gloomba is essentially a "Dark" Goomba. They live deep underground, in areas such as Toad Town Tunnels or the Pit of 100 Trials. They are always unhappy, and are much more powerful than their above-ground cousins. A Gloomba gets its blue color from living without sunlight, but it is unknown if they naturally obtain their red shoes.
