Mine Goblin is another type of Goblin, this difference is due to the different environment they live in (a mine or a cave and not a forest) .

First mentioned on Redhead's POV sidestory on Day 27. But, first seen Day 142.

Found in the Labyrinth City Purgatory, in the Mine of the Cyclops dungeon. 

A goblin with dark skin who had all of the muscles on it’s body torn off by an ice axe.

Rou says it tastes so-so. Although it wasn’t delicious, he wouldn’t go as far as to say it was an unpleasant taste.

A common occurrence in this place.
