'''Sea Serpent''' is an obstacle in [[20,000 Lums Under The Sea]], the fourth world of [[Rayman Legends]]. It appears in the level [[There's Always
A Bigger Fish]], and possibly in the boss level [[A Madman's Creation!]]. It is first summoned by [[The Magician]] to eat [[Rayman]] and his friends. After chasing the heroes throughout the level, it dies when the heroes pull the drain plug, sucking in all of the water in and the serpent itself. It appears on the cover of the game, and in many promotional trailers for the game.
It appears as a huge Sea Dragon with many legs and spikes throughout it's body, much like [[Murray]] and [[Mechanical Serpent]]. It is a ferocious beast with many sharp teeth. It is possible that it and mechanical serpent are the same thing, but this remains unconfirmed.
