This submission is based upon fire coral
. It is aquatic without being a Water-type, similar to Stunfisk, and aligning it with the Dry Skin ability. I realise some people have worried that it doesn't look "Poison-type" enough, but it is based on fire coral: Fire coral IS poisonous, and my design goes a step further to include stinging tentacles and sludge cannons - I feel like the Poison bases are adequately covered. ^_^ This Pokemon has a firm, flexible shell over most of its body, extending into coral-like arms that can spit poison or shoot flames. It has venomous tentacles that it also uses to absorb its food, and it can pull these back into its body as depicted in Supp1 below. These tentacles are fragile, and can tear off, but regrow quickly. It has a special mechanism that allows it to emit flames underwater even at very high-pressure depths. If it does not have occasional contact with water it can dry out and in emergencies it can absorb moisture from the air, desiccating the nearby landscape in the process.

(slightly older design, but it's still exactly how this Pokemon would use Flamethrower)
