Duck element (ConceptTopic, 6)

From Compile Worlds

Duck element is the exclusive element of the Ducks, and therefore also the Sasserblaster and the Giant Evil Ekoronian Cannon of Doom. No known character aside from the ducks themselves are known to resist, absorb, or take mortal damage from this element, and other than the aforementioned weapons, nothing attacks with the element either.

Perhaps one day FGF Research Co. will look into this bizarriamite.
