Sandshrew and Sandslash

Sandshrew
The Mouse Pokémon
Type: Ground
Official Registration #: 27
Entry: A pangolin-like pokémon native to dry grasslands and deserts. This pokémon possesses a rough, sandy hide capable of soaking up moisture from the dirt around it as it digs its burrows. Because of the consistency of its hide—along with its unique, sponge-like ability—sandshrew don’t need to drink much water and, in fact, shy away from it in all its forms as much as possible. Except, of course, in Alola, where sandshrew have adapted to become ice and steel types for reasons that surely make sense in a region that hosts plenty of other habitats a sandshrew can congregate in.

Sandslash
The Mouse Pokémon
Type: Ground
Official Registration #: 28
Entry: The evolved form of sandshrew, by battle experience. This pokémon is covered in sharp spikes, which are actually hardened sections of its hide. These spikes serve a largely defensive purpose: when threatened, a sandshrew will curl into a ball, forcing its spikes to stand on end and discourage physical attacks. In rare cases, a sandslash may be able to spin and move while in this position, thus crashing into enemies and obstacles. Such sandslash have also been noted to be faster, slightly bluer, and somehow “cooler” than other members of its species.
