Read more ↓Tentacool, the Jellyfish Pokémon, is a Water/Poison type first introduced in Generation I. It is known for its translucent, blue, jelly-like body and two large, red, gem-like eyes. Tentacool typically inhabits the shallow waters near coastlines, often found floating aimlessly or swimming with its two tentacle-like appendages. Its diet consists primarily of small aquatic organisms, which it ensnares with its stinging tentacles. In the wild, Tentacool are often seen in large groups, especially during mating season, and are known to be quite aggressive if disturbed, attacking with a barrage of poisonous stings. It evolves into Tentacruel starting at level 30. In the Pokémon anime, Tentacool and Tentacruel frequently appear as obstacles for protagonists, notably in episodes where they threaten coastal cities or marine environments. Its design is clearly inspired by real-world jellyfish, incorporating both their ethereal beauty and their potential danger. Despite its commonality, Tentacool holds a significant place in the Pokémon ecosystem and lore, representing the diverse aquatic life of the Pokémon world and often serving as an early-game encounter for trainers exploring coastal regions. Its dual typing gives it unique strengths and weaknesses, making it a versatile addition to many teams, particularly in early generations where Water and Poison types were less common.
