Much of a Ranbleko’s time is spent in and around the waters of ponds and lakes they call home. These amphibians eat any insect they can get in their mouths, although they prefer more toxic meals. Their long, sticky tongues make catching winged prey quick and easy. Because of their diet, they are also poisonous, and their bright colors warn off potential predators. If they do get injured by attack or accident, Ranblekos have advanced regeneration and are capable of regrowing lost limbs and even some vital organs. Rudimentary lungs allow them to breathe while on land, and they often make loud, chirping vocalizations that resonate in the deep sacs on their throats. Capable of hopping nearly fifteen times their body length, they are quick to dodge potential dangers and return to the safety of their aquatic home. While underwater, Ranblekos breathe through their skin, although some have also been observed with external gills fringing their face. Most of their swimming power comes from their tail, and they use their webbed feet for more precise maneuvering.

The creatures that dwell in this rather desolate world still display some diversity in appearance, eating habits, and social behavior. Whether they have fur or feathers, skin or scales, their unique genetic makeup allows for a variety of colors and markings within each species. Despite limitations in food sources, herbivores, omnivores, and carnivores are all present in the food chain, and each species requires specialized care within a laboratory. Although the artificial setting of housing units and breeding pods precludes most opportunities to study true interspecific behavior, the interactions within and between species has been studied extensively in the wilderness by scientists daring enough to venture beyond the outpost’s walls.
