Bananenpudd

I used around 20 pp up on my pokemon in front of the elite 4 and logged off to play it the other day, but suddenly when i logged in again only one pokemon still got its pp it should have. There is no pp up in my inventory, any way to fix this?

Just found this and wondering about how much i can sell it for [MEDIA=imgur2]mdqVUsX[/MEDIA]
