An African hippo gets his foot stuck in the mud, and lots of animals try to help, but even the biggest and strongest is unable. The hippo needs your help to get free. Your child will delight in this ebook, which makes them the hero of the story (you can say their name and gender as you read). The imagery of the hero is androgynous, meaning it could be a boy or a girl. This is the non-enhanced edition of the ebook, as per the requirements of the platform you are purchasing it on. The moral of the story is learning to use your intellect (and engineering knowledge) rather than brawn to solve this sloshy, mucky problem. There's some information about the concept of leverage, a group game and a comprehension questionnaire at the end, which may interest educators.
