Fauna is the fairy in Sleeping Beauty who gives Aurora the gift of song.
At Aurora's christening in Disney's 1959 film, the three good fairies each intend to give the baby princess a blessing. Flora grants beauty, and Fauna grants song. Before Merryweather can finish announcing her own gift, Maleficent arrives and places a curse on Aurora: on her sixteenth birthday, she will prick her finger on a spinning wheel and die.
Fauna is sometimes confused with Flora because their names sound similar and both are among Aurora's fairy guardians. Flora is the red-dressed fairy who often takes charge, while Fauna is the green-dressed fairy associated with the song blessing. Merryweather, the blue-dressed fairy, does not give the song gift.
Merryweather's most important contribution comes after the curse. She cannot erase Maleficent's magic, but she changes the fatal outcome so Aurora will fall into a deep sleep instead of dying. The spell can then be broken by true love's kiss, allowing Prince Philip to rescue her.
