But the big question - is Dobby there to bewitch the quaffle when it comes back down to earth?

I'm going to keep it 100 with you all - I don't know the first thing about Harry Potter. In fact, AJ told me to type the line above about quaffles and waffles and stuff. But she showed me this video, and said that it was cool, and she said that you Harry Potter fans would love it. So, here ya go. Enjoy, muggles.
