Onix design thing

For whatever reason I really wanted to draw crocodile!onix again, and hopefully with my improved drawing ability it's better than the ones I've drawn before.

Added some 'researcher' notes to easier jot down my ideas. It's not realistic per se since it allows for the pokemon to have mystical abilities (like the drilling technique here).
Also how else do you explain an animal that moves at 80 km/h underground?! I didn't even mention the speed. Presumably their top speed is considerably lower, but they ambush prey from underneath as many other designs already show. Hm hm!
