The Lizzey is a Maxis-made creature, present in the final game. It first appeared in the Spore Creature Creator, although the only difference between the Creature Creator and final versions are the feet.
Lizzey are not very powerful. They can do weak bites and weak strikes at their enemies. However, they are good runners, in case they have to chase the prey, or if they must escape from battle.
For socializing, they can do non-impressive sings, poses and charms. They are, however, good dancers.
