[Wirt rolls his eyes at the leaf blower, but he's actually kind of relieved Dipper sees his point. He's been a little worried that maybe he's just being paranoid, but at least it makes sense to someone else.]

W-Well, no, I mean-- I could live with hat hair if I had to, I guess. But I kind of got this all out of our attic without asking? I'm pretty sure my mom would be annoyed if I lost it all in another dimension.

[Especially the cape. The hat he could probably replace if he had to, but the current plan is to get home, glue the fluff back on it, and pretend like he never took it, and he'd rather go with that. He's not a great liar, so he'd probably get busted as soon as his mom realized they were down a santa hat.]
