Idalia is the name of two fairies who appear exclusively in the Nintendo DS game series, Disney Fairies: Tinker Bell and Disney Fairies: Tinker Bell and the Lost Treasure, and neither form appears in the original film their respective games are based on.
Disney Fairies: Tinker Bell
The Disney Fairies: Tinker Bell version of Idalia looks somewhat similar to Qana, except for the fact that she is mostly in pink and appears younger. She is a recently arrived flower fairy (and apparently the only fairy of this talent to ever appear in the franchise most likely due to the abundance of garden fairies) who has a love for flower petals, and will trade things for them.
By exchanging 10 yellow petals, the player will recieve a random number of a random colored Light Bead, while exchanging normal pink petals, the player will receive a random number of the Cherry Blossoms item, which are often necessary for Spring preparations.
She also seems to have a slight fascination with Tinker Bell's appearance, often remarking that she is pretty and does not know how she does it.
Idalia also has a passion for the perfumes of certain flowers and is said to experiment with different ones to find out which smells better on her.
She is often found in the Flower Garden, but can sometimes be seen in other areas.
Disney Fairies: Tinker Bell and the Lost Treasure
This Idalia is drastically different from the one found in the previous game, having a completely redesigned appearance (she appears somewhat similar to Magnolia of the last game) and even suddenly becoming a garden fairy.
