Meet Tweak, an extraterrestrial being whose luck went from bad to worse when he was kidnapped from his native planet as a zoological specimen, then sold to Cursed Earth slavers. He might not look out of place next to most terrestrial animals, but his species is about as alien as they come.

Despite his rather beastly appearance, Tweak’s species boast a technological advanced culture and limited psychic abilities. They live in vast subterranean cities and mine their food source directly from the planet’s crust — in the form of rocks and minerals. That’s where those powerful, oversized claws come into play: for crunching down granite and quartz into bite-size gravel.

How does Earth life match up to that? We certainly have “mineral-crunching” bacteria that love stone soup (hold the broth) as well as old Tweak here. But as far as creatures of comparable size go, he really has no equal.
