The limapin split from its ancestor and moved into the Badger Limestone Caves in the middle of the taigapin's habitat, where it feeds on the fauna of the cave. Though it prefers the larger creatures, its young will sometimes eat bubblehorns or wingworms. Its tridactyl hands have become longer and tougher. It will use these to catch its prey and either slice open its neck with its sharp mandibles, or keep it at a distance and suffocate it with its hands if it puts up a fight. Its mandibles have also changed. The top mandible has split in two for a better grip on its prey. The lower mandible is still the same: smooth and sharp.
Its legs have adapted for optimal movement on the limestone. All four legs have developed suction caps; it can now walk on the walls and even the ceiling of the cave. The limapin is a silent and solitary hunter. It will sneak up to its prey, sometimes by crawling over the ceiling above it, then suddenly falling off to surprise the unfortunate creature. It can turn around while falling to land on its legs. If the prey escapes, the limapin will almost never chase it, except when it feels extremely hungry. Most of the time though it will just turn around to find another victim.
While it can still change color, it doesn't use this ability very often, as the light green they usually are is the best camouflage in the limestone caves. It does use bright colors to scare another limapin away from its favorite hunting spot, and sometimes even stripes and dots for more complex communication. However it is less social than its ancestor and will only meet other members of its species for mating or by pure accident. The vocal sac on its forehead can still be used, but the color patterns are now its primary means of communication.
