You mean like the eyes for Pokemon and Earthbound characters that use layered textures for eyes?
And lol, Scraggy.
PAT0's is more like "texture replacement" that will replace the texture under the animation it's being used.
it's mainly most used by pokemon and Earthbound, it's even used by many like king dedede's eyelids, all the toonlinks mouths textures and eyes ect.
it would be perfect if Oshawott is over Toonlink cause his massvise PAT0s so his eyes and mouth will also "move" like happy eyes, sad eyes ect :]
scraggy is happy about it
