Tentacool

Tentacool resembles a box jellyfish. It has a light blue, clear body with two large, transparent, red crystals on each side of its body, and one small one in the middle. It has two small eyes with black pupils and no visible irises near the base of its body. It uses its two tentacles laced with stinging cells to poison its prey. The tentacles extend from beneath its round, blue lower body, which has a cape-like formation in the back. Its entire body is made of 99% water and the remaining 1% contains the organ that makes its poison.

Tentacool absorbs sunlight and refracts it using water inside its body to convert it into beam energy, as seen in the anime. It is also able to control Pokémon it touches with its tentacles, which can regenerate. Tentacool travel throughout the world using ocean currents. It will sometimes wash ashore and shrivel up due to dehydration, though it remains equally as dangerous. Tentacool may be revived if it is thrown back into the sea.
