How about Poliwag learning Mega Punch... What's up with that?

Punching is done with a fist... POLIWAG HAS NO FISTS!!!

What's it gonna punch with, it's ****ing tail!?

Or maybe Torchic being able to learn Seismic Toss - those feather duster wings can't even get it off the ground - how are they gonna huck a Machamp or a Venusaur around?
