Ug-A-Lug: Four Cavemen and a Prehistoric Pencil by Jill Lewis and Simon Rickerty

For anyone who's ever imagined what might happen if your doodle comes to life. A hilarious tale of cavemen, sabre-tooth tigers - and a giant pencil!

A little boy is doodling cavemen. He gives them all names - Colin, Clive, Carlos and Flint - and then goes to get a drink. As he leaves, he accidentally knocks over his pot of pencils. And that's when something amazing happens. One of the pencils drops into his picture, where the cavemen have now come to life!
