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.
