This cheery story explores the gamut of emotions of four young friends. A lovely way to celebrate happy times, as well as acknowledging the times when we feel "scratchy, grumpy, and yucky", too.

An introduction for the youngest readers to the different feelings they experience, from sad to funny, angry to sunny, and even lost and small.

This is not a tale for the faint-hearted, but children who enjoyed the bottom humour of Giles Andreae's Pants will doubtless love it

Must be the most revolting picture book of the year! . . . This book needs a warning to parents - they're going to have to read it over and over again - children will absolutely love it

Adults will be revolted and struggle to read to the end; children, I'm afraid, will just love it

There is something about snot which intrigues at this age and Morris the Mankiest Monster provides plenty of toenails, pustules and other delights from a disgusting but friendly monster

Children will absolutely love it - I will leave adults to make up their own minds . . . The illustrations are wonderful - full of grisly details that children will adore, and they will delight in reading the story to you. Great fun!

Any book that has an embossed green bogey on the cover has already got my vote. This frankly vile book is a complete and utter joy from beginning to end . . . A revoltingly good treat for young children

Sarah McIntyre certainly does not hold back with her illustrations of Giles Andreae's hilarious rhyming words . . . Sarah's illustrations are all beautifully drawn, with an incredible attention to detail that will have children poring lovingly over the pages

Comes across as an infant Fungus the Bogeyman in the sort of humourous rhymes of text Giles Andreae does so well
