Liam didn't have any of the relevant Pokemon with him. As they walked, a Sandshrew came up from the ground below.

"[i]Sandshrew, the Mouse Pokemon. Sandshrew's body is configured to absorb water without waste, enabling it to survive in an arid desert. This Pokémon curls up to protect itself from its enemies. At night, it burrows into the desert sand to sleep.[/i]" Liam noticed the Sandshrew looked hurt.
