Minecraft 1.17 Mob Idea - Grimroach

The overworld have their own Arthropods (Spider), so does the normal caves (Cave Spiders). But what about the Deep dark? Thats when this idea comes, not only to give the Deep dark a new mob, but also to make a better progression. 

Grimroaches remember slightly cockroaches, but big (like cave spiders) and black, grimstone-like, sort of blending in with the caves. The Grimroaches really like grimstone, and you better not break any close to them, because they will quickly attack you. They might drop Grimroach Meat, which can be cooked, being a food alternative in the deep dark. 

Thanks to the name changing of the grimstone, a good alternative name would be Slateroach
