>>50970386Agreed, yup. I'm not saying it's fitting, just putting some stuff about Convergent evo here for people to read. A diglett adapting to the new niche would just be a regional form.
I think another good reference for convergent forms would be Arvalis art. In making Pokemon that are biologically feasible, he comes up for a substitute for something like floating electric balls. Like a bunch of crabs who fold up, or pangolins that use static.
