The only universal aspect of Creeper Geist development is their incredible hunter, which causes them to eat anything in sight. They become more than just aggressive - as a species, they are suicidal, attacking whatever comes this way, regardless of size, number and danger. They will eat flesh, bones, plants, appetizing-looking rocks. Their jaws stretch out, exceeding the limits of their mouth, bulging outward with a set of sharp teeth. They do not fight as other animals do, they bite down until they manage to rip a chunk of flesh out, which they immediately swallow down. By the time they take hardier prey down they will often have a stomach full of meat already.
During mating season, their crest will become aflush with blood - this signal is the only thing that can temporarily distract the C. Geists from their craving, and after mating they will often attempt to eat each other, resulting in a bizarre case of sexual dimorphism in which the females are typically larger, further endangering newborns. How the species survives is anyone's guess, as it seems to be driven only by their huge need for food.
Due to the raised pelvis, the seismic organs move to the front of the body, some atrophying in the process. With the C. Geists frequently breaking unheard-of speeds, the seismic organs are frequently torn by friction, and become little more than bundles of constantly expanding nerves, only the Creepers' incredible metabolism allowing them to recover quickly enough to be functional.
