When the monkeys awakened, they were thirsty. Mappo was going down, right away, to the ground and get a drink at a water-pool near the family tree.
"Wait!" called his father, stretching out his long, hairy arms. "I must first look to see that the tiger is not there, Mappo."
But the tiger was far away, so the monkeys scrambled down and took long drinks. Then they crawled back into their tree again.
For two or three days after this, Mappo, his brothers and sisters practiced their new lesson of opening cocoanuts, until they could do it as well as Mr. and Mrs. Monkey.
Meanwhile they had gone off together, a little way into the woods, looking for different things to eat. Mappo used to go a little ahead of the others.
"Be careful," his mother warned him. "If you get too far away from us, the tiger will catch you."
Then Mappo would come back.
One day, after the monkeys had opened some cocoanuts and eaten out the white meat, Mappo thought of a good trick to play on Bumpo or Jacko.
Down on the ground, under the family tree, were some empty cocoanut shells. One was almost whole, with only a small piece broken out.
"I'll put that piece of shell back in the hole," said Mappo, "and it will look as though it had not been opened. Then I'll give it to Jacko or Bumpo. They'll think it's a good cocoanut, and try to break it open. Then won't they feel funny when they see it's empty!"
