The Hand Of The Ancients has just been added to Habbox which means it's recently been added to the Habbo servers. I believe this is the items to complete the 2nd part of the quest as at the end it asks you to "Find the second artifact, the left hand of Quackamon".
Edit:
Scrap that, it's been added to the shop:
You are able to stand on the hand and also place furni on top of it.
