Tily is a small fairy girl who is exclusive to Rayman Arena. She is an unlockable character. Her in-game leit motif is a high pitched, up beat song, to portray her playful personality.
Many fans have discovered that the name Tily is almost a combination of the names Betilla and Ly. It is possible that she is the daughter of one of them, being a fairy. She bears more of a resemblance to Ly, possibly meaning that the two are related, either as Mother-Daughter or Sister-Sister, or that they are cousins.
