Ducky

Ducky is a Maxis-made cell found in the Cell stage at Level 4 as epic-sized, but are soon turned into small preys and then disappear from the player's view.

Duckies, when epic-sized, appear constantly. If the player's cell has Spikes, they can stab Ducky's long eyes and easily defeat him. Ducky may run away if hit. They are named Ducky probably because they have long jaws resembling duck beaks.
