“ ‘Let’s try making ourselves into a tower,’ said Duck. ‘Good idea!’ said Bramwell. Little Bear climbed on top of Rabbit’s head and Rabbit hopped onto Duck’s beak. They stretched up as far as they could, but then Duck opened his beak to say something. Rabbit wobbled, and they all collapsed on top of Bramwell.”
