Tentacool and Tentacruel

In order to construct a new hotel at Hutber Port, a developer hires Pokémon trainers to get rid of the Tentacool because they inhabit a coral reef that the developer needs to build over. Team Rocket try to scam the developer and get rid of the Tentacool, spreading a mixture of soy and vinegar over the area. Their plan backfires, however, as the Tentacool evolve into gigantic Tentacruel, which attack until Misty saves the day.
