Oi Frog!
Book 1 of 8 in Oi Frog and FriendsView the full series
A modern rhyming picture-book staple built on one brilliantly simple rule: animals must sit on things that rhyme with their names. It is funny, loud, highly repeatable and excellent for phonological awareness.

What’s it about?
The story.
Frog does not want to sit on a log. Cats sit on mats, hares sit on chairs and mules sit on stools, but Frog is not convinced that this rhyming seating system is fair. As the animals explain who sits where, the pairings get sillier, stranger and more satisfying to say aloud. Oi Frog! is a high-energy rhyming comedy with a wonderfully clear pattern: children can hear the joke, predict the rhyme and join in quickly. Kes Gray's text turns phonics-adjacent wordplay into pure silliness, while Jim Field's expressive animals make each page feel bright and theatrical. It is a strong repeat-read choice for preschool and Reception-age children, especially those who enjoy rules, rebellion, animals and ridiculous sound-play.
“Sit on a log, said the cat to the frog.”

In the classroom
How it works in school.
A riotously funny rhyming series built on rhyme — superb for joining in, predicting rhymes and playing with words.
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 it lands
Why they love it.
Why kids love it
The specific pleasure is the rhyme being completely airtight — cats on mats, mules on stools, gophers on sofas. By the third page a three-year-old is shouting the next animal's seat before the adult reads it. The rhyme picture book that taught a generation that words can be a toy.
- Talking to animals
- Breaking the rules safely
- Trickery and cleverness
- Being understood finally
Why parents love it
The picture book that reads better the louder you do it. Quoted on playgrounds across Britain, and the foundation of one of the most reliable join-in read-aloud series for the three-to-five shelf. The original — and still the best place to start before the sequels.
- Shared humour
- Quick to read
- Bedtime appropriate
- Educational for adult too
