The Al Packa is a Maxis-made creature, present in the final game. It is based on the animals of the Camelidae family of real animals. The name is taken from "alpaca", though the Spore creature has significantly less fur.
Al Packa was seen as an epic in Galactic Adventures trailer fighting an epicBrontoth.
They are deadly carnivores, and while fighting they have a horrifically powerful bite capable of rending flesh, as well as a moderately powerful charge to daze their prey to allow them to work their massively strong jaws.
