Sandshrew

Description
This Ground type has a very efficient hydration system, so it can go for 5 days without water at any one time. Disliking water, it lives in deep burrows in arid areas. It can roll itself instantly into a ball. If it fell from a great height, this Pokémon could save itself by rolling into a ball and bouncing. To protect itself from attackers, it curls up into a ball. It lives in arid regions with minimal rainfall.
