Pink Ice

In South Africa, a talking Pink Panther is the owner of a diamond mine and has unearthed a large gem. He puts it in his safe, which has a combination lock that functions like a telephone dial, and a man tunnels into the safe and filches the jewel. The Pink Panther suspects gophers of perpetrating the theft, but a dastardly pair of rival miners, operating the neighboring DeBoors mine, have taken the diamond and claim it and the diamond-yielding territory as their own.
