Feef

The feef has replaced it ancestor in the Yokto Mountain Lake and Yokto Polar River. Unlike it ancestor, the feef has reactivated some of its genes that allowed it to evolve a pair of front legs; these legs are used to crawl around the mud. The feef has evolved into an ambush predator and in order to stay hidden, the feef has also lost the glowing spots of its ancestor. Another adaptation that helps it catch its food is that its tongue has evolved to look like a branch from a pioneer twinkiirobranch. With this adaptation, it will lie and wait for a tadpole to swim towards its mouth and when it gets close enough, the feef will clamp down on its prey and devour it with its re-evolved teeth. For other species, it will not stick its tongue out, instead it simply waits for the prey to get close and snaps it up. Otherwise it will tear off chunks of carcasses.

Though the feef gets most of its oxygen by absorbing water through its skin, it has also re-evolved nostrils that allow it to breath air when there is not enough water. The feef has also adapted to its environment by being able to hibernate whenever there is little water; when it hibernates, it buries itself in the mud. This adaptation has allowed it to be able to move into the Drake Boreal. However, the feef is uncommon in this area, instead they are most common in the riparian, swamp, and river zones. The feef's reproductive method has reverted to that of the rest of the Carpazoa lineage, the female lays eggs in the water and the male fertilizes them, next the female scoops the fertilized eggs into its mouth and holds the babies in there until they are fully grown.
