Apalu lives with his friends in the forests of the rainbow island. He spends most of his time high up in the trees, where he plays, eats and sleeps. Sometimes he climbs down and runs into the village of the rainbow elves. There he is the source of much excitement, because all of the elves think he is so cute and love to feed and stroke him. Yammo enjoys his time with the elves, but in the evening he returns to his friends in the forest.
