Read the excerpt from "the crab that played with the sea."

then the little girl-daughter put up her little soft brown arms with the beautiful white shell bracelets and said, ‘o eldest magician! when my father here talked to you at the very beginning, and i leaned upon his shoulder while the beasts were being taught their plays, one beast went away naughtily into the sea before you had taught him his play.

and the eldest magician said, ‘how wise are little children who see and are silent! what was the beast like? ’

and the little girl-daughter said, ‘he was round and he was flat; and his eyes grew upon stalks; and he walked sideways like this; and he was covered with strong armour upon his back.’

and the eldest magician said, ‘how wise are little children who speak truth! now i know where pau amma went. give me the paddle! ’

so he took the paddle; but there was no need to paddle, for the water flowed steadily past all the islands till they came to the place called pusat tasek—the heart of the sea—where the great hollow is that leads down to the heart of the world, and in that hollow grows the wonderful tree, pauh janggi, that bears the magic twin nuts. then the eldest magician slid his arm up to the shoulder through the deep warm water, and under the roots of the wonderful tree he touched the broad back of pau amma the crab. and pau amma settled down at the touch, and all the sea rose up as water rises in a basin when you put your hand into it.

‘ah! ’ said the eldest magician. ‘now i know who has been playing with the sea; ’ and he called out, ‘what are you doing, pau amma? ’

and pau amma, deep down below, answered, ‘once a day and once a night i go out to look for my food. once a day and once a night i return. leave me alone.’

then the eldest magician said, ‘listen, pau amma. when you go out from your cave the waters of the sea pour down into pusat tasek, and all the beaches of all the islands are left bare, and the little fish die, and raja moyang kaban, the king of the elephants, his legs are made muddy. when you come back and sit in pusat tasek, the waters of the sea rise, and half the little islands are drowned, and the man’s house is flooded, and raja abdullah, the king of the crocodiles, his mouth is filled with the salt water.’
