Sandshrew

, known as the Mouse Pokémon, are a species of brick-skinned mouse-like Pokémon found in several regions throughout the Pokémon world. Despite its name, Sandshrew's appearance borrows more from the armadillo or the pangolin than from the shrew; its primary means of defense when threatened is to instantly curl up its body into a ball, leaving only its tough skin exposed. When it is rolled up like this, Sandshrew has the potential to withstand many attacks, as well as being dropped from a great height (also similar to hedgehogs). Sandshrew's natural environment is buried in the sand in arid, sandy locations with very little moisture, such as a desert. It chooses this habitat to keep its hide as dry and tough as possible, while the sand also provides it with good camouflage.
