Our heroes arrive at Hutber Port, where a ferryboat line runs to the mainland. There they meet a cousin of the old man’s competitor from Acapulco who, having recently acquired a great deal of money, is trying to construct a huge luxury hotel, turning a coral reef area into a tremendous resort. This section of coral reef, however, is very important to the Tentacool and Horsea that live there. When a huge school of Tentacool interferes with the construction of the hotel, the cousin and a group of young people organize a campaign to drive them away, offering a reward of $10,000 to anyone who can repel the Tentacool. Naturally this draws the attention of Team Rocket who attempt to get rid of the Tentacool by spreading a mixture of super secret stun sauce over the ocean. Their plan backfires, however, transforming the Tentacool into a gigantic Tentacruel which begins a fierce counterattack against the humans. In order to defeat this reign of terror, Ash, Misty, Brock and their Pokemon are drawn into a battle that will require more than just strong combative skill. (thetvdb.com)
