"Arlo is a very tired lion, and he's tried everything to get to sleep. But the grass is too prickly, the trees are too noisy, and his family wriggles awfully too much. Goodness! How is an exhausted lion ever to get a wink of shut-eye? Luckily, owl has a few tricks up her sleeve and Arlo couldn't be happier to give them a whirl. Perfect for reluctant or troubled sleepers.
