He'll see Howl trying to climb up a tree. It's not really working - he's already had to sacrifice his jacket just to get up to the first branch, and now there are wolves snapping at his heels. The wizard is currently trying to dissuade them by chucking branches at them.

"Oh, go away already!"

To be fair, he's not nearly as terrified as he could be. It's more annoyance than anything. Somehow wolves are not as terrifying as a gigantic bear.
