Question

During the middle of the night thomas keeps saying something about there isnt stocking so he can't keep this gift here, and that its tough sneaking into poeples houses, what going on?!?!

Answer 1

Thats a holiday where you have to have socks on your sock hook(read cheats on that)and if you have them he will give you somthing and if you dont just say that.

Answer 2

If you become close friends with Nina (over 200 FP) and give her a ball of yarn, she will knit socks that will automatically be hung on the hooks in your home. Thomas will put a random gem in your stocking for Christmas.
