I try to not worry about that, since “biology” tends to take a back seat whenever this kind of magic is involved. The literal atoms and their interactions aren’t important, what’s important is that now your arms and legs and ears and tail are super squishy and soft and comfy! How can you move them without muscles? Because they’re yours, silly, of course you can move them!
… Does that make sense? It goes from making physical sense to making metaphysical sense, I guess. I-I hope this helps your friend… Have a good nap!
