This cute little lad wants to go dragon hunting with his cousin, Sir Brian the Bold but he can't get his armour on because of his huge nappy.
What is he going to to?
Well, he's going to use the potty of course. Only, he can't decide quite how it works. Oh dear!
Don't worry, there's nothing gruesome in this book. Only wonderful illustrations by the hugely talented Laura Ellen Anderson.
