Plentdiver

The plentdiver split from the plentiver and is now fully aquatic. It has lost its small legs, and its leaf-wings have evolved into fins, meaning it can no longer fly. Its back rudders have also developed into back flippers, and its butt-nostril has developed into a butt-snorkel. It eats only plants and has developed a flatter beak to graze on the river grasses. It will float on the surface to sunbathe and collect the sun rays to recharge, as well as digest the grasses. Its neck has grown longer so it can graze with its butt-snorkel on the surface and still breathe. They eat in social grounds and one will always look out while the other puts their head underwater. If a predator is near, it will slap the water surface with its leaf-fins to warn the others.
