Tentacruel is a large, jellyfish-like Pokémon. It has clear, light blue body that has two large, red orbs on either side and smaller orb in the center. Its eyes are visible in its round lower body, which is black. Extending from its lower body are two blue, beak like appendages and numerous grayish tentacles. Its red orbs glow whenever it is excited or agitated, and it may alert others to danger by stridently flashing them. They are also capable of refracting sunlight, storing energy, and firing ultrasonic waves.
Tentacruel's primarily light blue body helps it camouflage in the water. It has a total of 80 tentacles, which it can readily extend during hunts to ensnare its prey before immobilizing it with poison. Its tentacles can absorb water to stretch even further. Most of these tentacles are hidden and kept short, leaving up to 14 exposed. However, it tends to lose tentacles as it ages. Tentacruel lives in underwater rock formations and can be found throughout the ocean.
