Tentacool

Tentacool is a Water/Poison-type Pokémon resembling a jellyfish. It has a translucent, blue body with two large, red crystal-like orbs on its head and a pair of tentacles. It uses its tentacles to ensnare prey and can emit ultrasonic waves to communicate or defend itself. Tentacool is often found drifting in the ocean, and it can dehydrate if left out of water for too long.
