With things like the Big walker 2 and their nymphs presenting a much more prevalent threat than things like the occasional Bug-Upper, populations of Liserlap further specialized for speed and agility and gave rise to the Liserbok. The legs of the Liserbok have become even longer with the two upper joints on each leg having more muscles to provide more force as they make their bounds across the “Dingus Scrub”. The longer stride and large muscles mean the Liserbok can run extremely quickly, easily outpacing all of the predators in their local ecosystem by the time they evolved, though their single hoof on each leg having become larger to better absorb the shock of hitting the ground at high speeds while the anus-tail has become even longer to make sharp turns and keep their balance while running. Liserbok are also known to leap into the air to clear obstacles like a fallen thorntower or a shallow ditch. The species will also jumping into the air in moderate hops against certain predators like Hulk-Uppers to display their speed and agility and show they are not worth chasing. To lighten up the load, the Liserboks have also become smaller than their ancestor, though they are still larger than things like the Unguliserd and their long limbs make up for their size in terms of stride length. The smaller size does mean the Liserbok can only contain the flora they consume for shorter periods of time than their ancestor and so they need to eat more vegetation to get a similar amount of energy. The derived grinding systems of the Liserbok that are inherited from their ancestor do partially make up for this, with their throat’s strong muscles still being capable of compressing the throat inwards and upwards so it can act like a “tounge” with the large grinding plates on said “tounge” helping to grind their food into a pulp to make extracting energy easier than swallowing bits of flora whole. With their smaller size, the Liserboks can’t reach tall flora as easily and so they are more dedicated grazers, with a larger upper lip allowing them to better grab food that can then be brought into their mouths.

The camouflage patterns of the Liserbok have become much more specialized to fit the “Dingus Scrub”, so they can sometimes avoid detection from danger while their sharp senses help them spot their own dangers. Their infrared vision still means the Liserbok can see well at night, though almost all of their foraging hours are during the daytime since they can rely on their speed and agility to avoid danger. The species still often travels alongside larger herbivores such as the Lawnmower Turdle since their sheer size can deter most of their threats like a Bug-Upper. Meanwhile, the radiation organ has devolved even further, with the lens being almost completely gone and the radiation organ itself being reduced to pretty much nothing. A large number of Liserboks completely lack the organ altogether, since it does not serve any purpose at all. The sail of their Liserbok has become reduced in length compared to their ancestor but has become much taller to help individuals in a herd keep track of one another and communicate since the species is deaf. It also is used to show the fitness of an individual and as such is used for courtship during the breeding season. The reproductive habits of the Liserbok have hardly changed, with the species only mating when the rains arrive within the "Dingus Scrub" so the produced young have an abundance of vegetation to feed upon. The way they breed has not changed at all from the forest dwelling Unguliserds, with two individuals budding next to each other that then merge together and exchange genes. Then, the Liserbok pair also irradiates the buds to help further mix up their genes. Then, the merged bud would split into 4 genetically distinct offspring. This allows the Liserbok to quickly adapt to any changes in their environment, such as an unusually long drought or extra heavy rains resulting in abundant flora growth.
