Biology
Sandshrew is a bipedal mammalian Pokémon, but runs on all fours in the anime. Its brick-patterned yellow hide is dry, tough, blends in with desert sand, and protects its soft white underbelly and muzzle. Sandshrew has blue, almond-shaped eyes, a pointed snout, and triangular ears with white insides. Its tail is thick and conical. It has two long claws on each foot and three sharp claws on its forepaws, which are used to burrow.

Sandshrew spends much of its time hidden underground in deep burrows. It only emerges to lunge and drag in passing Bug-type Pokémon. Sandshrew can quickly curl into a tight ball to protect itself from great falls and opponents, but may also throw sand at attackers. While its body can efficiently absorb water to facilitate life in the desert, Sandshrew has been found in caves as well. It also lives deep underground in nests it has created from digging tunnels. Should hard rocks get in the way of digging, Sandshrew will use its sharp claws to remove them before continuing to dig. If it is too wet, its skin becomes wrinkly. It dries itself out by using the geothermal heat near a volcano.
