All day long, the zoo animals roar and make noise. When they lay down to go to sleep, something keeps them awake: a new baby beebee bird isn't tired and sings all night long. When morning comes, all the animals are still tired. To prove their point, the animals make noise all day, keeping the bird awake. The next night all the animals, including the baby beebee bird, are fast asleep.
