As the local bruhs of the Dingus water ways further improved in their art of active predators, a population of Grazing Jello-Fish would respond by becoming much bigger. At this size, they would also become much more herbivorous, with energy obtained from flora becoming more prominent than the energy obtained from their fusiotrophic metabolisms. This would result in them becoming a distinct taxon known as the Pulpmouth. While at first glance it may resemble its ancestor, the Pulpmouth has made some major changes to its anatomy. The first immediate difference is its much larger size, as a large bulk of its diet consists of tough and woody vegetation which then required a larger blind gut to better digest it and in turn it needed a large body to house said gut. This larger body size also meant the Pulpmouth was safer from the local predators though the calcium carbonate armor embedded within their thicker skin still provides protection as well. The species also has developed a beak-like tooth on their upper lip to help them bite and crush the tough flora they consume. They also can then grind it up so it is more easily digested. Any waste products will still be vomited up by the Pulpmouth in the form of a pellet. In some ways, the Pulpmouth has hardly changed at all from their ancestor and relatives, like the circulatory system of hemooranganin which helps support their multicellular bodies with the circulatory system also still surrounding the digestive system. Although it relies on it less than their ancestor, the Pulpmouth can still get some of their energy from radiation although they have lost the ability to 'zap' organisms with the radiation since they instead rely on their size, armor, and powerful bite to deter anything that tries to mess with them.

When it comes to breeding, the Pulpmouth has not changed much from their ancestor, as they release "gametes" into the water. When they encounter those of another individual, the two "gametes" then fuse together and then split into two developing youngsters. The youngsters are more vulnerable to predators and so they will seek out adult Pulpmouths for protection until they are old and large enough that they can move off on their own.
