It was an ordinary afternoon. Stevie and Khloe stepped outside into the backyard only to hear a little sound like a baby crying. What was it, they wondered? To their surprise it was two tiny kittens.

Join Stevie, Khloe and their good friend Suki on their quest to solve the mystery of the green cat.
