After 7 years, it will crawl on land and shed its skin, becoming the dangerous Mandibligosa, an omnivorous airborne threat that fights with great speed and ferocity.
Mandiblulu is a large, aquatic Neopteron, with compound eyes that glow a deep green color, 4 thick burrowing legs, a pair of spines which act as gills on its rear carapace, and a hardened, moss-green exoskeleton covered in root-like extensions to camouflage itself in its swampy home. It has primitive breathing holes that allow it to breathe on land for long periods of time.
It's often dormant, lying in wait for its main prey, Epioths, to swim by. When they do, its labium launches out and grab it, crushing its prey's shell, and bringing its meal back to its hungry, slicing mandibles, and is adequately consumed. If it grabs prey with a harder shell, it sprays digestive enzymes that, if sprayed on a hunter, inflicts Dragonblight and Corroded.
