When the moon comes up over the mountains, all the animals in the rain forest go to sleep. But, what's that noise? And how can the animals make it stop? "Wuaaah, wuaaah, wuaaah." The noise goes on and on. Cuddled up inside an abandoned box, someone is sobbing, and one by one, the animals try to comfort the little one. But with each offering -- of a blanket, some fresh water, mango, and so on -- the small creature settles only briefly before wailing once again. Finally, Tiger disappears and returns with the little creature's mother. Peace is restored, until . . . "Wuu, wuu, wuuuuuu," cries a child in a nearby village. This time, it is the little creature who solves the problem by yelling out, "That child must have a kiss! Then we can all go back to sleep."
