Tentacool

The jellyfish-like Tentacool usually drift in shallow seas. Fishermen who hook them by accident are often punished by their stinging acid. In "Tentacool and Tentacruel," a developer hires Pokemon trainers to get rid of Tentacool that are living in a coral reef so he can build a hotel on the same site. This attracts the attention of the always scheming Team Rocket, who try to scam the developer and get rid of the Tentacool.
