[Help] Nogg Skeleton To Deviant Fish Yaaarr! Pirate (male)

[Mercer]

So... i was looking for some help on how i could do this. I play on a 1.12.1 private server after quiting retail and im a nightelf female warrior. And when i use nogg and get the skele i wanted it to show me as human male pirate (The Delight fish one or the one from halloween i dont mind what) but as i cant find the pirates model anywhere in the game files i got no clue on how id do this, Maybe its a spell edit? anyone with idea's ^^?
