I don’t always do hunts in SL, but I did the Halloween Swaginator Hunt for fun. It was quick hunt with only 4 things to find! You must wear the free HUD from the Swaginator gift-giving station before you start the hunt.
Important tip: When you teleport to your locations, be sure to stand close to the grave/giant pumpkin before you click on it to receive the gifts and the next hint. The hint is spoken in local chat, so if you’re too far away, you won’t see the next hint, and the object will not repeat it (frustrating).
