The tale of the valiant ninja frog by Alastair Chisholm

Sometimes being small means you can be the biggest hero of all! Jamie and Abby are camping with Dad and they tell a bedtime story together. This story will star their favourites: a prince, a witch, a thief and some bears. ‘And the frog!’ says Abby. This time there’s a terrible ogre who’s stolen all the keys to the kingdom. No one can get into their homes! No one can start their horses! It’s a real mess. Our heroes must sneak into the ogre’s castle and retrieve the keys. But when it comes to the crunch, only a tiny froggy hero, who’s also a ninja, can defeat the mighty ogre!
