What’s it about?

The story.

Here's the challenge: study a close-up photo of a mystery animal, then decide whether you're looking at its bum or its face. Turn the page and the full photo reveals the answer, along with a fast-fact box explaining how each creature really uses its extraordinary rear or front end. Kari Lavelle mines the wonderfully weird world of camouflage and trickery, from the Cuyaba dwarf frog, whose backside is marked with fake eyes to scare off predators, to the Mary River turtle, which can actually breathe through its bottom. The premise is pure playground giggles, but the science underneath is genuine and surprising, and the interactive guess-and-reveal format turns each page into a game. Bright, photographic and packed with puns, it is exactly the kind of gross-out non-fiction that hooks reluctant readers and animal-fact obsessives alike, and it is just as much fun read aloud to a whole class as it is one to one.

Fit check

Right for your child?

Where it lands by age

A guess-and-giggle fact book for roughly 4 to 9s, working brilliantly read aloud to a class and independently for readers of about 5 upwards. The gross-out premise hooks reluctant readers, with real animal science for older ones.

Why it lands

Why they love it.

Why kids love it

Guessing whether a close-up is an animal's front or its bottom is hilarious every single time, and the reveals are packed with genuinely surprising facts. A turtle that breathes through its bum? Children will want to share every single page.

  • Trickery and cleverness
  • Being a detective

Why parents love it

The guess-and-reveal format sneaks proper natural-history facts past even the most reluctant reader, and the photographs are genuinely fascinating. It is loud, funny and just as good read aloud to a class as at home.

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