The vegehopper evolved from Russian swarmers which stayed near the surface and banks of the river. With the evolution of the bank balgae and then the mavrophyte and bunopad these swarmers took advantage of this new food source and the new lack of predators. As such, they split from the main population of Russian swarmers and became bigger. They have developed a simple jawed mouth with hardened skin to crush their new food. Their leaf fins have developed into flippers which can be used as legs to hop around on land. They have adapted two separate breathing chambers, one which acts like gills to breathe in water and one which can breathe air, though only for a short time. They switch between these chambers depending on the circumstance, and also carry water in the gill chamber when they are out of the water to extend their time spent there. They have adopted an amphibious lifestyle to stay near their food and to better catch sunlight, but they never stray far from the river. They will often sit on top of tangle root plants to bask in the sun. Due to their larger size and lack of predation, vegehoppers reproduce in smaller numbers than their swarmer ancestors and give birth to only one or two young at a time.
Also, vegehoppers taste just like Earth's cucumber.
