"Why on earth would you pick at your snowboard if you were busy having fun in the slopes?" Well, I could say that's because it wants the snowboard to keep sliding, although he doesn't understand why it has stopped on _white terrain_ (it shold slide you know?). So he goes back to where it knows it can slide down again. I think it's the same when it went from one roof side back to the other.
