Honestly it's a pretty fantastic mail-carrying bird, they should plot how to best turn Percy into a human snowman.

"I think Muninn might have higher ambitions."

"It's Christmas, that's the time when we put all our higher ambitions aside and give in to the petty ones."

A snowball lands on George's head.

He laughs and throws one at Muninn.

He catches it and throws it back.

He dodges, looks at his twin—

—and both of them start attacking Muninn in sync.

Muninn turns out to be really good at dodging, although he can't always manage the throw-it-back trick.

And this does give Ron time to target the twins.

Fun!

Then, cold, wet, and gasping for breath, they return to the Gryffindor common room where they can sit in front of the fireplace and get warm.

Muninn steals Victor's hot chocolate.

After a meal of turkey sandwiches, crumpets, trifle, and Christmas cake, everyone—or, at least, Ron—feels too full and sleepy to do much before bed except sit and watch Percy chase Fred and George all over Gryffindor Tower because they've stolen his prefect badge.

Muninn steals it back and drops it on Percy's head.

"Thank you, Muninn."

The twins laugh.

"I'm the prettiest!" he says smugly, landing on Victor's shoulder again.

Soon they make their way to bed, after a pretty great and exhausting day.

Victor looks at his bundled-up invisibility cloak. If he'd had this, he wouldn't have had to run from Filch, and he never would've seen the three-headed dog, and might not have been able to make all the inferences that led him to be worried about Voldemort's followers stealing the Philosopher's Stone - but just because he wouldn't be worried about it doesn't mean it wouldn't be happening...

He goes to sleep, somewhat troubled.

The morning brings him no answer. Nor does the rest of the winter holidays. And eventually the students who went home for the holidays return.

"Hey! How were the holidays?" she asks when he sees Victor and Muninn.

"We had a snowball fight. Muninn won."

She looks at Muninn and raises an eyebrow. "I call shenanigans."

"Special delivery," he says.

Giggle. "Get many presents?"
