As Merryweather is about to give Aurora the gift of happiness,[1] Maleficent makes her appearance and curses the princess to die when she pricks her finger on a spinning wheel's spindle before sunset on her sixteenth birthday.
The three good fairies arrive at the christening of King Stefan and Queen Leah's newborn daughter, Princess Aurora.
Maleficent prepares to leave but also decides to give a "gift" to Aurora by cursing her: before the sun sets on her sixteenth birthday, she will prick her finger on a spinning wheel's spindle and die.
The three good fairies plot against Maleficent, since they were not convinced that King Stefan and Queen Leah's response to the curse (declaring that every spinning wheel in the kingdom be burned) would be enough to stop the witch.
Years later, on the day of Aurora (whom they call Briar Rose)'s sixteenth birthday, the fairies plan a surprise for her, and so they send her berry-picking in the forest (while warning her not to go too far and not to speak to strangers).
The lights from their magical fight begin to escape through the chimney, catching the attention of Maleficent's raven and thus revealing their location.
The quarrel ends with the dress getting both of the pink and blue colors, and then the three hear Aurora's arrival back to the cottage, prompting Flora and Merryweather to stop their argument and the three prepare their surprise (as they do so, Flora secretly turns the dress' color into pink, then Merryweather secretly turns it into blue).
They weep in sadness, but Flora decided that, in order to prevent everyone from being heartbroken, they put the entire kingdom to sleep until Princess Aurora awakens.
While falling asleep, King Hubert tries to tell Stefan of his son being in love with a peasant maiden, which makes Flora realize that Prince Phillip is the young man Aurora has fallen in love with and the one fated to break the curse and save the whole kingdom, so the fairies fly back to the cottage for him.
The three good fairies also appear in Disney Princess Enchanted Tales: Follow Your Dreams during the "Keys to the Kingdom" segment.
Before leaving with Flora and Fauna, Merryweather still is worried about Aurora and she gives her wand to the princess in case she needs any assistance and warns her to be very careful with it.
The fairies manage to deliver the speech in time, and are about to return when Merryweather reveals she had lent her wand to Aurora when she was not supposed to do so.
They are in the last shown crowd before Timon and Pumbaa start the movie again sitting between Terk (from Tarzan) and Br'er Bear (from Song of the South).
They first appear in Kingdom Hearts II at Yen Sid's tower, giving Sora his new outfit after he wakes from his year-long sleep, as well as the Star Seeker Keyblade and the ability to use Drive, and later witnessing Maleficent's return to power.
In Kingdom Hearts Birth by Sleep, the fairies appear in their homeworld, the "Enchanted Dominion", talking with Ventus about Aurora and Phillip and later assisting him in his battle against Maleficent.
They do not make a physical appearance in Kingdom Hearts III, but are mentioned by Yen Sid as the creators of the cast's new clothes.
