[Three]

It's cold. Groot hates the cold.

Which is only natural, when you think about it. Plant-based lifeforms need a certai climate in order to thrive, and this is most certainly not any such environment. His Guardian uniform keeps him a little insulated, but wearing layers can really only do so much good when you're not warm-blooded.

There's a scowl nearly permanently etched into his wooden face as he stomps his way into the nearest building, eager to get out of the cold and point the snow out from in-between his toe-like roots. It takes him a moment - his haste to get to warmth had made him careless - but eventually the Floral Colossus notices the tell-tale signs inside the house:

This building is already inhabited.

Immediately, his guard goes up. Groot raises his two wooden fists, ready to strike back if anyone is foolish enough to try to ambush him. He's managed to go this long without getting into any fights, but if someone here wants to make him into firewood they're going to have to work for it.

"I AM GROOT!"

For those of you in need of a translator, that's Groot-speak for 'Show yourself, coward!'
