The Snorkel Snake is featured in Yoshi's Story. It would prowl the Yoshi Sea waiting for an unsuspecting Yoshi to attack. It resembles a large, white serpent with green spikes and a large fin for the tail. It's head is a large ball with red eyes, flippers, and a spout for a mouth. It is invincible, at least underwater. Since Yoshi can't throw eggs underwater it's weakness is never seen.
It is unknown if Snorkel Snakes are a species.
