Tentacool resembles a box jellyfish. It has a light blue, clear body with two large, transparent, crystal-like red spots on each side of its body, and one small one in the middle. It has two tentacles laced with stinging cells. The tentacles extend from beneath its round, blue lower body, which has a cape-like formation in the back.

Special abilities
Tentacool absorbs sunlight and refracts it using water inside its body to convert it into beam energy, as seen in the episode Tentacool and Tentacruel. It can also ooze poison if threatened.
Behavior
This Pokémon shoots beams from its crystal-like eyes, and are often found floating in shallow waters.
Tentacool can be found throughout the ocean, usually congregating in places where warm currents and cold currents come together, and where minerals are plentiful. They are extremely common in Kanto, Johto, Hoenn and Sinnoh.
A school of Tentacool appeared in a flashback in A Cacturne for the Worse. May fears them due to being surrounded by them at one point, and her mother trying to catch her, thinking that she was a Tentacool.
One of the members of the Pokémon Fan Club in Vermilion City apparently bathes with her Tentacool on a regular basis. She is seen again with her Tentacool in Volume 14 during the Chairman's call out to all Trainers to send their Pokémon to help the fight in Ilex Forest.
Tentacool's body is largely composed of water. If it is removed from the sea, it dries up like parchment. If this Pokémon happens to become dehydrated, put it back into the sea.

In the anime, Tentacool and its evolution, Tentacruel, have both been shown to possess psychic abilities. However, in the games, Tentacool can only learn four Psychic-type moves; none inflict any damage.
Tentacool's name is a combination of tentacle and the adjective cool. Its Japanese name may be a combination of 目の敵 menokataki, enemy, and 水母 kurage, jellyfish, or alternatively, it may be a pun on the Japanese expression 目の毒 menodoku, "poison to the eye" (referring to a tempting thing but one that must not be looked at), considering that its evolution's name is ドククラゲ dokukurage.
