Good point, but maybe the more animal-like are work pets.

I get what you were going for here, but I think Maud would prefer an array of Rock-types that are actual living rocks rather than these mere rock-skinned animals. I’m talking about guys like Gigalith, Carbink, Nosepass/ Probopass, possibly Crustle and/or Barbarnacle (Crustle is a living display of sedimentary layering and Barbarnacle is about seven giant barnacles forming a body by attaching themselves to actual rocks), and maybe even Sudowoodo (it’s a tree-shaped rock and it could represent petrified wood). Golem is still good, that guy is definitely living rock.

“My next Pokemon is a rock-type. They’re all rock-types.”

These things were awesome, but now they officially rock.

 
Suuuuuup.
