The Mine Goblin is a type of Goblin with dark skin. This skin color is due to the different environment they live in (a mine or a cave) .

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

It's commonly found in the Labyrinth City [ Purgatory ]'s, [ Mine of the Cyclops ] dungeon. 

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.
