Ariados

Ariados is a dual-type Bug/Poison Pokémon.

It evolves from Spinarak starting at level 22.

Biology
Ariados is a red Pokémon that resembles a spider. It has purple eyes, a pair of white mandibles, and a white horn on its forehead. Around its abdomen are two black stripes and there are two black spots and a yellow spinneret on its rear. The spots and spinneret together form a pattern similar to a face. Ariados can produce thread from both its spinneret and its mouth. It has four yellow legs with two purple bands each; on its back are yellow structures similar to its legs with a single purple stripe each. Its feet are tipped with tiny hooks that allow it to climb ceilings and vertical walls.

Ariados makes its nest in the depths of temperate and tropical forests and leaves after dark to hunt prey. While Ariados wanders in search of prey, it spins a single thread from its rear that leads back to its nest. When prey is captured, it is wrapped in thread and then attacked by fangs. Ariados then drinks the victim's bodily fluids at leisure. Sometimes, it will instead release prey with only a single thread attached. The thread is then followed to both the caught prey and its friends. Ariados and its pre-evolution Spinarak are the only known Pokémon that can learn Toxic Thread. In the past, this was also true of Spider Web.
