<DIV>Fizzlebert Stump lives in a circus. His mum's a clown, his best friend is a bearded boy, and he sticks his head in a lion's mouth every night. Other than that, he's pretty normal. <br/><br/>When Fish the sea lion goes missing Fizzlebert tracks down the runaway beast to the Aquarium, with its piratical owner Admiral Spratt-Haddock, invisible octopus, and colour-coded fish. But the Aquarium has problems of its own. Fish (not Fish the sea lion, <i>fish</i>. Keep up.) are going missing, and the Admiral blames the circus. Can Fizzlebert solve the mystery, avoid an over-enthusiastic crocodile, and find his friend?</div>
