Why do zebras have stripes, leopards spots, rhinos horns and camels humps? Tinga Tinga Tales tells a young audience what might have happened. There was a time when Zebra was skinny and white all over. Eagle discovered the Great Cave. All were interested except for Zebra, who was happy munching and munching on his grass, getting fatter and fatter. Tortoise thought that a new black coat might help Zebra hide better in the savannah, so Zebra tried it on, but the coat was too tight and it ripped. Zebra has been stripy from then on.
