Book review 11Deep Trouble

I really astonish this story.Billy and his sister, Sheena, are visiting their uncle Dr. Deep on a tiny Caribbean island. While swimming in the reef, Billy encounters a giant octupus-like sea monster. Luckily, he survives. Of course, Dr. Deep, Sheena, and Alexander don't believe him when he tells them about the monster. Later, Billy hears Dr. Deep talking with people from the local zoo, who have been convinced by local fishermen that they have seen a mermaid with blond hair and a green tail, and they want Dr. Deep to capture her and put her in the zoo. Billy is caught listening, but he is let in on the secret. The next day, Billy tries to hind her, Sheena tags along, and Billy is almost killed by a hammerhead shark. A green fishtail attacks the shark and saves Billy's life. The two are caught in a net by Dr. Deep and the mermaid is put in a tank, much to both Billy and the mermaid's dismay. With the exception of the little-seen monster, this book isn't considered to be scary. The book was later adapted into Goosebumps Graphix Terror Trips. However, in Grapix, the mermaid has a dark pink tail and either brown or red hair. It is unknown because the book is in black and white, and her description is never given.
