A jungle is a good place to hide things, which makes it a perfect place for puzzles. Spot the differences between snakes, join the dots to raise a sloth out of the page, count the parrots perched in the trees and keep going, spread after spread of leafy scenes with something to find in each one.

The trick of the book is the coating. Every page is durable and wipe clean, so a dry wipe pen line disappears with one pass of a cloth and the favorite puzzles can be done again tomorrow, and again after that. One book, effectively endless.

Behind the play sit the fundamentals: counting, observation and the pen control that writing is built on. Twenty four pages by Kirsteen Robson, illustrated by Manuela Berti, for jungle explorers aged three and up.

Also on the shelf here: Wipe-Clean Airport Activities, twenty four wipe-clean pages of dot to dots, mazes, matching and spot the difference set across one busy airport, with the pen on the cover.
