Reward #6, hinted at being an easy target for snowballs fights, has no gift kiosk, as well as I can determine. The hud TPs you to the Winter Wonderland landing point for the last hunt. It does not TP you to the snowball arena, as the hint suggests. The Hud Giver is there, but on the reverse side of it, the image is the reward giver. The front side gives you the hud directly, the reverse side sends you the hud again via Caspervend. I cannot find another reward giver in any of the 4 Winter Wonderland Sims. I think this was never actually set up.
