A sandstorm has buried Animal Junction in sand, which is perfect for the meerkats, scorpion and camel that stop by for a visit. Zoboo, Chris and Martin explain how each of these creatures is suited for living in a dry, desert climate. Jackie walks along the beach looking for shells, but she doesn't take any with her because some of these shells are homes to the hermit crab. She decides to build a beautiful sand castle for her crab friends instead.
