Why do zebras have stripes, leopards spots, rhinos horns and camels humps? Tinga Tinga Tales tells a modern, young audience what might have happened. There was a time when Crocodile didn't have a bumpy back. His skin was smooth and he had to be careful of the hot Tinga Tinga sun. One day while napping, Crocodile got sunburnt and fell into a deep sleep. Lion warned the animals to be on their guard as the wildebeest had returned and could stampede at any moment. Crocodile missed the meeting, snoring under the hot sun. The animals tried to warn snappy Crocodile, but it was too late and the wildebeest stampeded over him. From that day on, Crocodile has had a bumpy back and has been grumpier and snappier than ever.
