Planet Calipsis is a real anomaly, on it is a race of small and oddly cuddly looking super-predators, known as the Callis. Out of everything the Callis could hunt, Callis exclusively hunt other predatory species, even pretending to be injured and mimicking the sounds of other creatures to do so. When encountered with something that doesn't seem like a predator, Callis will be very friendly, as these species are typically hunted by what the Callis wants to eat.
