This is a fully illustrated book suitable for reading to younger children and for reading by those who can read. The setting is an imaginative frog world, where Freddie is a little frog, who, unlike the other frogs in his pond, isn’t green. He’s blue! When he finds out that he is different, he can think of nothing else besides trying to become green. However, none of his friends has any idea how to help him do this. Freddie’s little sister, Felicity, has a bright idea. She persuades the rest of the frogs in their pond to seek advice from the biggest-frog-in-the-world, the enormous King Frongo. They all go on a journey to find the King. When they do, it is King Frongo’s wife, the stately and beautiful Queen Francesca, who solves the problem.
