What caused the Dinosaurs to die out? A massive meteorite? The Ice Age? Hacking scandals? No it was underpants, as every child knows - particularly after they've read the latest in the 'Underpants' books from Claire Freedman and Ben Cort. The team have successfully given us instant classic 'Aliens Love Underpans' and 'Santa Loves Underpants', now they turn their focus on the stone age and the most important invention since the wheel, the Y Front.
Dinosaurs covet mankind's invention, and lots of squabbling ensues. This delicious rhyming tale is a must for any dino-obsessed child, helpfully taking them through a few well known Dino species before their pants-based demise.
Bouncy fidgety storytelling at its best. Toddlers will love it to pieces.
Charlotte's best bit: The Diplodocus and his tiny briefs
Daddy's favourite bit: The Triceratops, of course.
