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.
