Little Hippo loves to pretend, and today he is playing a doctor. He tries to examine Big Hippo, Very Tall Giraffe, Giant Crocodile, Elephant, and other patients. But not everyone plays the way Doctor Hippo expected. Especially not Lion. Lion does not want to play Doctor Hippos game. When he lets out a huge roar, the little doctor races home to find that Mama Hippos medicine is the best of all. Jonathan Londons reassuring story is perfectly matched by Gilles Eduars warm and whimsical illustrations.,
