The monkeys that live at the foot of the Mbuno Hills in Africa love to play games. One day while playing Elephant in the Middle with their large friend, their ball, a nut from an ancient baobab tree, rolls into a cave where the troop of monkeys never go. It is dark inside and possibly filled with horrible beasts! When they venture in, they discover instead that the walls are covered with paintings of animals. Elephant shows the monkeys how they too can create artwork using their hands and feet as stamps and mud as their medium. But things are never quite as easy as they seem.
