After changing into his handsome swimsuit, Eino made way to the front of the class where he took some of the gillyweed and consumed it. It tasted like wet and cold boiled snake tongues, and yes, he had eaten those. They were rather yummy, though not when they got cold. They were also a bit slimy but that would facilitate digestion, right? Soon enough he could sense the effects of the plant taking effect. His hands and feet were not webbed, like a duck's and something, though he could not see what, was happening to his neck. As he pressed his fingers against it, he could feel small opening suggesting he had grown gills. After making sure he had his wand with him, Eino followed everyone else into the lake.
