Paradox Shellder - Rockface Knuckle

So here's a Shellder with a fist-like shell and barnacle-ish 'nails', with spikes that break off to illustrate how rugged it is, and of course allude to Cloyster. The initial typing was Grass/Rock with an emphasis on the need to keep the tongue and plants moist, which would've suggested a non-Water Shellder that lived on cliffs eventually became water-type. In the end I kept the water typing and added Steel to be super effective vs rock and suggest that metal it consumes goes to its main shell.
