I collect them all though I have long since stopped doing it on my noob accounts since I don't even play on them. I got the hat though I've never really worn it so it may as well have not been there. I find most of the later holiday items ugly having only worn the squirrel ears by choice.
I used that Grim reaper hood when skilling in f2p as there weren't really any other hoods available to me and I had not yet discovered how awesome the black wizard hat was.
I've not really worn any of the other holiday items, except the candy cane sometimes.
tbh I wonder if Sna ky posted on the hlf access fred and said Sha ky is maxed give them access the mod might get confused look up my stats and then gib access to sna ky
