The saggulper evolved from the puff-tongued plenthog and has completely replaced its ancestor. Since all the silkworms are gone and have been replaced by the poison sagworm, it has evolved to eat it. It has built up immunity to the poison of the sagworms. It also has developed purple camouflage to hide it from predators in nearby biomes. Its photosynthetic sails and front limbs have almost disappeared, since it spends all day on its back 2 feet. Its butt-nostrils have developed into a supporting tail. It can sit with its head facing up with its mouth open and tongue extended, waiting for a sagworm to land. Once one lands, they gulp it up. Its vision is extremely poor, since they hunt by touch.
