The 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 a Dark Teensy 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 as a huge beast that attacks Rayman and his friends, much like its role in the actual game, but it only appears in one level.
It appears as a huge Sea Dragon with many legs and spikes throughout it's body, much like the Shrimp king and the Mechanical Dragon. It is a ferocious beast with many sharp teeth. It is possible that it and the Mechanical Dragon are the same thing, but this remains unconfirmed.
