Hippowdon
A genial concept if you ask me. Whereas Abomasnow is an alright abominable snowman (though, a wooden one, that's certainly creative) just like you'd expect one to look, GameFreak really turned the concept of hippopotamus around when they made Hippowdon. Usually an aquatic mammal frolicking in the Nile, but GameFreak figured out that they might as well place its habitat a few thousand kilometres westward. Whereas the Earthly hippo lives in and around rivers, Hippowdon thrive in sand. They swim around in quicksand, burrow in the dunes, and even have powdery blood. Sand is water, indeed, for Hippowdon. It has the ability to manipulate it like Water Pokémon manipulate water, and is just as comfortable underground as overground. Hippowdon is also good stat-wise, and has a wide array of moves in its arsenal.
