Avan's not paying attention to anything else, is he? Not Popp walking out to the main part of, or walking back half an hour later... It is the act of a friend to get him to take a break, maybe- no ok ok Popp has to be honest with himself he just really wants to chuck a snowball at him. It is winter and this is what winter and friends are for.

He chucks a snowball at him. Think fast, nerd! He yells a warning while it's in midair.

"Kacrackle!"

He does not know this spell. You're allowed to just yell things if you want to.
