Description:Charging into everyone's hearts, it's Kayode the southern white rhino. Born at California's San Diego Zoo, the calf weighs around 150 pounds, but once he's an adult, he'll be a whopping four to five thousand pounds, that's between one and two thousand kilograms. He's less than two weeks old, but already Kayode has a signature habit that sets him apart, says zookeeper Jane Kennedy.(0:45)
