What’s it about?
The story.
Hippos Go Berserk! starts with one hippo all alone, then builds into an increasingly ridiculous party as more and more hippos arrive. The book works as a counting story, a party story and a comic escalation machine. Its appeal comes from the contrast between simple number progression and the absurd energy of hippos completely losing control. The 45th anniversary edition expands the format into a larger picture-book-style edition, while older board versions remain part of its history. This is a key Boynton title because it shows her sense of rhythm and escalation in an early, iconic form. It is less bedtime-cosy than The Going to Bed Book and less concept-pure than Doggies, but stronger for party energy, counting and group chaos.

In the classroom
How it works in school.
A rollicking rhyming counting read-aloud — great for joining in and counting along.
A book children love that happens to support school — never a stand-in for the texts a class is taught with. Reviewed for the classroom · June 2026.

Why they love it.
Why kids love it
The specific kick is counting up then down — one lonely hippo, then two more, then three, escalating to forty-five hippos at a chaotic party, then everyone leaves and the count runs back. A three-year-old gets a maths book and a comedy in one.
- Friendship and belonging
- Animal companions
- Adventure and freedom
Why parents love it
The Boynton that doubles as a counting book — escalating party comedy, the count climbing to forty-five and back down. Useful for early numeracy without anyone mentioning maths. Reliable toddler-shelf staple.
