What’s it about?

The story.

The Oi animals have dealt with frogs, dogs, cats, puppies and even a duck-billed platypus, but the rhyme rules are not finished yet. In Oi Aardvark!, Frog, Cat and Dog face another round of animal seating chaos, with aardvarks and other unusual creatures making the wordplay bigger and more surprising. The series' appeal remains beautifully simple: say an animal, find a rhyme, laugh at the ridiculous thing it has to sit on. This entry is especially useful for children who enjoy unusual animal names and the pleasure of more challenging sounds. Kes Gray keeps the rhythm clear enough for preschool join-in reading, while Jim Field's illustrations deliver expressive, colourful comedy. It is not a deep story, but it is excellent language play disguised as pure silliness.

Why it lands

Why they love it.

Why kids love it

The specific kick is the harder rhymes — by the seventh Oi, the animal list has stretched into territory that requires longer words a four-year-old wouldn't normally meet (aardvark, mongoose). Children get to feel they've levelled up. The rhyme game gets sillier the more obscure the animal.

  • Talking to animals
  • Animal companions
  • Breaking the rules safely
  • Trickery and cleverness

Why parents love it

The Oi for a child whose vocabulary is starting to outpace the early picture books — the rhyme game introduces longer animal names and trickier sounds in a way that builds phonological confidence without ever feeling like a lesson. Good late-Oi choice for the four-to-five-year-old shelf.

  • Shared humour
  • Quick to read
  • Bedtime appropriate
  • Educational for adult too

Kes Gray

Writer · United Kingdom · b. 1960

Kes Gray is a British author born in 1960, best known for the bestselling Oi Frog! rhyming picture-book series (illustrated by Jim Field): Oi Frog!, Oi Dog!, Oi Cat!, Oi Duck-billed Platypus!, Oi Aardvark! and more. Each book runs on absurd-rhyme animal-on-X seating-chart logic, with deliberately silly word-play that lands well on read-aloud. Gray also wrote the long-running Daisy chapter-book series (Daisy and the Trouble with Zoos, …Life, …Maggots etc.), and Eat Your Peas. His voice is gleeful, child-aligned and quietly subversive, children typically love that the books treat absurd rule-fixation as a moral universe. A reliable read-aloud author for ages 3–7 (picture books) and 6–9 (Daisy).
