About This Book
Reach for this book when you want to turn a routine counting lesson into a moment of pure, high-energy joy. It is the perfect antidote to a rainy day or a restless bedtime, using rhythmic verse and silly illustrations to make learning numbers feel like an invitation to a party. The story follows a solitary hippo who invites more and more friends over until his house is bursting with ninety-seven exuberant guests. While it technically covers numbers one through nine and then works back down to zero, the real heart of the book is its sense of playful chaos and the warm feeling of being surrounded by friends. It is an essential classic for toddlers and preschoolers that proves math is anything but boring.
What Parents Should Know
Sensitive Topics
None.
Ideal Reader
A toddler who is just beginning to mimic sounds and numbers, or a preschooler who loves physical humor and wants to shout 'GO BERSERK!' along with the reader.
Parent Prep
This book is best read with varying volume. Be prepared to whisper at the beginning and end, and get loud and boisterous during the middle 'berserk' pages. It can be read cold with great success. A child who is resistant to counting practice or a parent looking for a high-energy read-aloud that doesn't feel like a 'lesson.'
Age Experience
For a one-year-old, the experience is about the rhythm of the rhyme and pointing at the funny animal faces. For a three or four-year-old, it becomes a literal counting game and a lesson in the concepts of 'more' and 'less.'
What Makes It Special
Unlike standard counting books that are often static, Boynton uses 'berserk' energy and absurdist humor to create a narrative arc. It is a rare concept book that feels like a short, complete comedy film.
Read plot summary
A solitary hippo decides to host a gathering. As he calls friends, they arrive in increasing groups (two on the phone, three at the door, four more, and so on) until the house is packed with hippos for an all-night bash. At dawn, the guests depart in descending groups until the original hippo is alone again, peacefully sleeping.
