Imaginations run wild as five friends try to find out who is making night noises... Turtle and friends are fast asleep in their hammock. Suddenly, Turtle wakes up and whispers, 'Do you hear what I hear?' And so begins a detective tale with a twist. Who's making the noise? The animals in the hammock - Turtle, Bat, Octopus, Bird and Goat - let their imaginations run riot. Is it a giant bat? Or a bird with a huge beak? Perhaps it's a tur - bat - octo - bird - billy? After much guessing, it turns out to be a friendly elephant. The animals invite Elephant to join them in their hammock and soon new wild imaginings about the night noises begin all over again. A witty nocturnal guessing game from the author - illustrator team who created Tangram Cat.
