The puritan in me says this is not something we should encourage, surely, toilet humour doesn't have a place in children's literature, does it? Then I remember my children's favourite TV show from the 1980s, the wolves, who farted and belched and made everyone, including me and Wendy, have hysterics. Toilet humour is harmless, and when it involved dinosaurs, there's no harm done, is there? This will make you laugh, and the illustrations are terrific, so what can go wrong? I'll put the puritan in me back in the sideboard and save it for something more worthy. This is brilliant!

The book, which is very reminiscent of Dr Seuss . . . is a lovely life lesson and deliciously naughty toilet-humour that will have young readers squealing in delight

If you love ponies like Katie does, then these books are perfect for you.

It may enccourage pony mad non-readers to start enjoying the reading experience. If it does that, and I'm certain it will, then one should take one's hat off to Katie

Shredder . . . stands out from the crowd - a first reader with a good plot, lively dialogue and engaging characters

Katie's illustrations are full of space, gentle colour and apparent simplicity. She also has a real way with drawing animals - Otto is a very handsome bear, a bear that you'll want to hug and make space for on your bookshelves
