This isn't much of a pressing question.
Anyway, in White 2 I had my Sneasel learn TM False Swipe and TM Toxic. In battle, however, False Swipe was at 5 PP out of 40, despite the fact I hadn't used it at all... Has anyone else experienced this? What is it?
That happens whenever you use an attack TM on a Pokemon. It's to prevent the player from spamming TMs to have infinite PP. So just take your Sneasel to a Pokemon Center and he'll be fine.
