The alolan muk can’t learn thunderbolt and thunder and is able to learn rock polish and stone edge. This adds such weird characterization to the forms.
That…
…huh.
That is weird.
Alolan Muk has a lot of particles sticking out of its body that could represent stones and thus justify Rock attacks. Maybe it can’t use electrical moves because it’s adapted for a more terrestrial lifestyle than the primarily aquatic Kantonian Muk?
