"Long, long ago, when the world was young, all the animals lived together in one country. In those days there were not as many tortoises as there are today but only one tortoise, Mbe, the ancestor of all tortoises..." In this idyllic world, a time of famine comes. Tortoise, in desperation, journeys out in search of food. At last he comes upon a palm tree with "thrice four hundred" ripe palm fruits. Atop this palm tree, one of the fruits slips from Tortoise's hand. Unwilling to give up even one of these succulent fruits, Tortoise descends. But the fruit has fallen into a hole, and Tortoise follows.
