Boasting the same eye-catching holographic foil stamping of the earlier books in the best-selling series, Rainbow Fish must brave the Sea Monsters' Cave, rumoured to be the most dangerous place in the ocean, to find healing algae to cure the ailing bumpy-backed fish. Warned by his friends about the dreadful denizens of the deep ndash; the giant rock monsters, the five-eyed globe fish, and the horrible creature with a thousand arms ndash; Rainbow Fish, accompanied by the little blue fish, musters all his courage and sets out on an exciting quest. In a satisfying and reassuring conclusion, Rainbow Fish discovers that by confronting his fears, it is possible to overcome them, and that sometimes there are simple, completely non-threatening explanations for fabled dangers.
