This is my pet rock Stanley. He is a very rare Painted Green Bumblebee Rock (Verdantus Bumblus). His only defence mechanism is to flip upside down and expose his unpainted side, thus making him look like an ordinary rock. I have had him for as long as I can remember and he has been my loyal friend for a very long time. Rocks make good pets because they never need feeding, exercising, toilet training or baths. They aren't very cuddly though!
