New mob: Mineratoris

Strongholds deserve a new Mob, right? With glowing eyes, they can dig tunnels, steal ores you have collected or even attack you! They can loosen ores, from coal and iron, to diamonds and emeralds (obviously, the latter two would be much more difficult to drop). Naturally aggressive, if you're not mining, they have 20 hearts and attack with an iron pick. It would have a variation for the Nether, and these would be found hidden between the blocks (Variation for Basalt Deltas). They could even be found in small campgrounds in the mines Similar to a villager, but without the classic villager's nose. Detailed with stone and ore details.
