Because of the challenge I'm doing on White several of my Pokemon are guilty of this. Tepig/Pignite is going to have Flamethrower, Flame Charge, and Fire Pledge. Oshawott has Water Gun/Hydro Pump, Razor Shell, and Aqua jet... etc.
And yeah they're all mixed as well because of the challenge (kudos to those who know what type of challenge I'm doing from that information).
