Oh my god I don't like this new-generation pokédex. Of course Grimer learns Zap Cannon, it just doesn't show because Zap Cannon is an old TM >_>

I'm very confused about why Natural Gift did damage though? Has it been shown in the animé? Because according to the game if no berry is held it has a base power of 1.

Aaaanyway Kage, I screwed up. Again. Sorry. I really should just stop battling people until I get my act together. This is embarrassing.
