The Duckulon is a Maxis-made creation appearing in the final game.
Duckulon are herbivores, with low stats. Their only mean of attack is a weak bite and a charge attack which stuns their foes for a few seconds. Their socializing isn't better either only being able to sing, which is at level 3.
They possess four graspers which can be used to manipulate objects, and they have two eyes facing forward. Not being fast the Duckulon are presumed to have stunned their predators with charge, then try to run away, it is unknown if they succeed to do this as their feet only give them a level 1 speed level.
