Make A Monster Contest
From Drunkapedia
As part of the 2005 Throne of Destiny Expansion, players were asked to submit suggestions for a new creature. The 1st place winner was implemented as the Thrungus. The second place winner was supposed to be added in a patch and was probably implemented as the mukkir though it has never been confirmed. And interestingly the third place winner bears a striking similarity to the Eater.
Full size versions of the submissions can be seen at here.
