Ludiv
A Ludiv is a type of fairy found in Rayman's world, most notably in the PlayStation version of Rayman 2, where Rayman must free them from cages, along with Denys and Greenbottles. They are said to be short-sighted and that they wear glasses - that without them, they end up stuck, lost and knocked to the ground.
A Ludiv (referred to only as a "pretty little fairy") appears in the bonus stages unlocked at the end of each level in Rayman 2 by finding all the level's Lums and breaking all its cages. In these bonus stages, the player controls a Baby Globox, which must race against Razorbeard's Lackey to the Ludiv. If the player wins the race, the Ludiv can grant Rayman gifts (health and/or magic fists).
In Rayman 3, Ludivs guard the Heart of the World in the Fairy Council.
Flips, a character from Rayman: The Animated Series, appears similar to the Ludivs, and may be one, though this is unconfirmed.
