Mareanie

Mareanie is a starfish-like Pokémon with a purple stalk-like body and ten drooping tentacles that resembles hair. It has a blue and purple color scheme, as well as what appears to be a gloomy expression. It has three teeth and blue eyes with yellow sclera and pupils. Each tentacle has three spines, except the one above its face, which is shorter than the others and has only two. When Mareanie attacks, this tentacle may extend to the length of the others and gain a third spine. It also has an additional yellow spine on the top of its head.

Bruxish is a natural predator of Mareanie, which in turn is known to hunt and prey on Corsola. Mareanie's main tactic is to harass it until the Corsola sheds its horns. As seen in the anime, Mareanie attacks first by launching onto the prey's face with all of its ten tentacles, then releasing the poison through its spikes.
