not sure i read this right but i'll try again .
open up ur wil editor and then select to open npc.wil if you run through the images u will see that what appears to be administrator is #8 then #9 so on and so forth, now with that siad on to the hard part ,Scroll down the images until you get to the NPC that resembles a snow man counting the different NPC's as you go then voila you will come across a snowman and a cristmas tree.
That is if you are as i said before you have the images in that NPC.wil file.
NOW on a final note this is a bit of help the snowman is appr number 48 in korean NPC.wil and cristmas tree is somewhere along the lines of 58 Hope this has helped you.
