Super Yellow Lum
A Super Yellow Lum is a special type of Lum which is formed by the reunion of five normal Yellow Lums. Despite the resemblance, it shall not be confused with the third player's Light Fly from Rayman M, in the Capture the Fly battle mode.
They are found in all versions of Rayman 2, except for Rayman Revolution, where each of the 1000 Yellow Lums must be found separately. They resemble larger Yellow Lums with a grinning face. When Rayman collects one, it counts as five normal Yellow Lums, suggesting that Super Yellow Lums are formed of five Yellow Lums joined together, in the same fashion that the Heart of the World is formed of 1000 Yellow Lums.
They can also be found in the Game Boy Color version of Rayman 2. The Super Yellow Lums in this version appear slightly larger, lack grinning faces, and have a value of ten Yellow Lums, making them twice as valuable as the Super Yellow Lums in the other versions.
