The logo for 20,000 Lums Under the Sea.

Dive in the depth [sic] of the ocean, in this spy world. Enemies are not a joke and you'll need stealth and skill to infiltrate the Ocean base. Be careful, the detections systems are top of the lines [sic] with laser beams detecting motions and patrolling toads equipped with night goggles. Be quick, be smart, play with the lights and the shadows to infiltrate this enemy base.

—Xbox e-manual, Rayman Legends

20,000 Lums Under the Sea, also known as the Sea of Serendipity in Rayman Adventures and the Iron Shell in Rayman Legends Retold, is the fourth world in Rayman Legends and its remake and the fourth world in Rayman Adventures. It is a water-and-machine based world, which takes cues from various spy tropes; for example, the James Bond theme can be heard during certain underwater sections. Several reoccurring elements from Rayman Origins, and the same name being used in Rayman Adventures, suggests that this world takes place in the Sea of Serendipity.

Description

20,000 Lums Under the Sea mainly takes place in an underwater base, with many pipes of different lengths and crates. Some parts of the base have windows where there's the familiar singing group of fish from Rayman Origins. Several areas in the base are underwater where the heroes use their swimming ability. The bodies of water are filled with rocks and mines and Dark Sentries. One part of the world takes place in a mansion, with red carpet and gold platforms. Mechanical gears at a late point can be seen, suggesting the fight against the boss of the world, the Mechanical Dragon.

• 
  Dark Sentries are one of the main enemies in the world.
• 
  Underwater Toads are one of the main enemies in the world. Some are seen here in a strange mansion room.
• 
  Murfy is used to push buttons and move objects throughout several areas of this world.

In Rayman Legends, after defeating El Luchador and the third Dark Teensy, Rayman and his team of heroes enter 20,000 Lums Under the Sea. They start out in the Mysterious Inflatable Island; the name is a reference to the bouncy, inflatable island they land on at the start of the level. They immediately begin to swim underwater after jumping off the island. Underwater, they have to get through the Dark Sentries, a very common enemy in the world that cannot be defeated.

They end up in an underwater base, where most Underwater Toads with guns reside at. The landscape of the base are pipes and crates. Murfy is needed in several parts of the Deadly Lights to move objects or push buttons to block the Dark Sentries' dangerous laser-like lights. A small mansion can be seen in Mansion of the Deep, with big aquariums, gold and a fancy red carpet. The heroes begin to alternate between swimming underwater and walking on the platforms of the base.

Later on, after surviving an ambush of Spy Toads on two pipe simulations of an elevator, they meet up with the fourth Dark Teensy. After pursuing him and rescuing a girl Teensie, he later whistles for a large, creature-eating sea dragon called Seabreather to hunt down the heroes. After a long chase in the water, the team pulls on a lever that drains the water, and defeats Seabreather. This shortly leads up to the Mechanical Dragon being activated. The heroes must take advantage of the recently acquired Flying Punch power-up to attack the weak spot of the Mechanical Dragon and destroy it. The Dark Teensy shortly after suffers the same fate as the first three.

Gloo Gloo, the music level of the world presumably is in the Sea of Serendipity from Rayman Origins. Elements from that world like the underwater caves, the wooden platforms and enemies like swordfish and a warship appear in this music level. This suggests that 20,000 Lums Under the Sea actually is in the Sea of Serendipity, though this is not confirmed.
