The Ape Monster is a Maxis made creature, present in the final game. They are one of the strongest and most social creatures in Maxis's Sporepedia.
Ape Monsters are very robust in combat and in socializing. When fighting, they can spit a strong poison and do a moderate stunning charge. They can also inflict a powerful strike and a powerful bite.
When socializing, Ape Monster is a great singer. He is also a good poser, but his best ability is dancing. Few creatures can outsmart the Ape Monster at dancing, especially when there's more than one.
