...Christmas on her mind
Literally :) The little Tree Girl has always been a fan of snow, Christmas, red&green and presents. She even started to look like a present herself, with that bow collar of hers.
She was born in the forest, right next to a family of pine trees that adopted her and told the girl everything about X-mas.
And she's very well rooted in tradition, if you know what we mean :) So don't upset her with things like "Santa is a myth", "your mom and dad buy you presents on Christmas" and so on. It's good to believe in this kind of things: look at her happy face and you'll understand :P
