Tentacool & Tentacruel

S1, E19: Our heroes arrive at Porta Vista, where a ferryboat line runs to the mainland. There they meet Nastina, a wealthy lady who wants to construct a huge luxury hotel and turn the island’s 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, Nastina organizes a campaign to drive them away, offering an incredible reward 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 soy and vinegar over the ocean. However, their plan backfires, as the potent potion transforms the Tentacool into a gigantic Tentacruel that begins a fierce counterattack upon Porta Vista. In order to defeat this reign of terror, Ash, Misty, Brock, and their Pokémon are drawn into a battle that will require more than just strong combative skill!
