Water Gun is useless on Totodile.
You should give him Waterfall if you want to give him a water move.
I wanna watch Hey Arnold...
i know. right after he learned water gun, i taught him Waterfall because it's a physical move and blah blah blah....
he knows Swords Dance, Ice Punch, Waterfall, and Dig (temporarily, so that i can EV train with the Shinx and stuff). he's a level 8.
