When Rayman Legends' developers got together to develop "20,000 Lums Under the Sea," they faced a seemingly uphill battle developing an underwater level,  knowing full-well that, "stereotypical gamers dread the thought of underwater gameplay." In the process of making it enjoyable and fun, the developers drew influence from quite a few established franchises in addition to referencing 20,000 Leagues Under the Sea, which served as the level's chief influence.

Chris McEntree, Level Designer at Ubisoft Montpellier, described the process of designing enemies whom traversed the level dressed like Splinter Cell's (another Ubisoft franchise) Sam Fisher, and, "[repelled] from the ceiling on ropes à la Mission Impossible," with, "a James Bond-style bass riff to score the whole thing." "There was even a shark dressed suspiciously like a familiar Bond villain to top it all off," Mr. McEntree added, "these references and parodies helped us strengthen the identity of the world, while at the same time injected a bit of humor into an otherwise uncharacteristically dark and serious environment for a Rayman game."

Rayman Legends was developed by Ubisoft Montpellier and published by Ubisoft alongside Nintendo for the PlayStation 3, Xbox 360, Wii U, PC, and PS Vita.
