"...it was horse-sized, covered with scales and standing on four rubbery legs with suckers like octopus tentacles. Its head was football-shaped with an antenna sticking up...The thing gave off this green, iridescent light." The crazy critter is a semiaquatic creature that lives in northern Idaho. It is mainly piscivorous, and will occasionally come on land to rest. The crazy critter is a distant relative of other amphibians, but has evolved many other features, such as the antennae used to smell and detect prey or predators nearby when in water. It lives in symbiosis with bioluminescant bacteria that run along its back in colonies, it uses these bacteria to communicate underwater with other members of its species.
