Desiryee has light pink skin, green eyes with purple eyeshadow, pink lips and dark pink body-tail with flower patterns. She wears a hot pink spiral shell-shaped hat decorated by two pink hibiscus flowers. A transparent light green veil attached to the hat. She has a pink flower-shaped symbol on her forehead.
Desiryee makes her first appearance in the movie in a scene where Omnia was captured by Tritannus and Trix. She and the other Selkies were trapped in a lighting barrier, preventing them from leaving it and were covered by something not letting them speak. Then she as well as the other Selkies follows the Winx to the place where the pearl was hidden and stays outside to warn Omnia if Tritannus escapes with the pearl. She was last seen in a final fight against Politea.
