comet

You were at home enjoying Christmas when you heard something hit your roof loudly. You saw a shadow fall through the window and decided to go see what it was. When you got close enough, you saw that it was a reindeer with a mint green harness and a collar with a headband that said "Comet".

...Hmm...

The reindeer woke up and stood up, staggering a little. He turned his head and when he saw you, he stood still.

umm...hello?

It seems to be okay despite crashing into your roof and falling from a height of two meters.
