Flora, Fauna, and Merryweather (also known as the Three Good Fairies) are the three deuteragonists, later real main protagonists of Disney's 16th full-length animated feature film, Sleeping Beauty, and supporting characters in its live-action remake, Maleficent.
Flora is the tallest as well as leader of the three and she is the one in pink, Fauna is the one in green, and Merryweather is the shortest and the one in blue. They are voiced by Verna Felton, Barbara Jo Allen, and Barbara Luddy, respectively, in the original film. In the live-action film, Maleficent, they are known as Knotgrass, Flittle and Thistlewit (also known as the Flower Pixies).
Flora, Fauna and Merryweather (also known collectively as the three good fairies) are first shown arriving at the christening of the newborn Princess Aurora. Flora begins by giving the child the gift of beauty, and Fauna gives her the gift of song. But before Merryweather can give her gift, Maleficent arrives and curses the princess to die before the sun sets on her sixteenth birthday. Fortunately, Merryweather hasn't managed to give her gift, so it ends up being the gift of sleep (actually, she means that instead of dying, she'll just fall into a long deep sleep until her true love kisses her).
Next, the fairies are having tea while Fauna suggests reasoning with Maleficent as the latter "can't be all bad" (but she really can, as Flora points out). Flora has an idea on how to keep Aurora safe, but prefers to keep it hidden between her and her followers alone, so they shrink themselves and hide in a little ring box. Flora decides to turn not Maleficent, but rather, the princess, into a flower, but Merryweather points out that Maleficent can send a frost, and Fauna points out that the bad fairy ruins Flora's nicest flowers. As Fauna then points out that Maleficent doesn't know anything good, Flora decides to turn the three of themselves into peasant women (with no magic or wings) while hiding the princess in a woodcutter's cottage deep in the forest. The fairies then take away the infant princess in order to hide her from Maleficent, her goons and her raven Diablo.
Sixteen years later, the fairies plan a surprise birthday party for Briar Rose (Princess Aurora while she is hidden), and send her out to pick berries as a distraction. Fauna decides to bake the cake (Merryweather had been doing all that, while Fauna was the one who had been sewing, during the hiding), while Flora tries to make the royal dress (as the birthday present) with Merryweather as the mannequin. Later, neither works out well, so Merryweather decides to get the magic wands. For this, they have to block up every cramming (unaware that the chimney counts) by locking the doors, closing the windows, and placing cloths on every crack, while Flora uses her magic to make the dress, Fauna makes the cake and Merryweather cleans up the room. During this, Merryweather and Flora fight over whether the dress should be pink or blue, alerting Diablo, who then finds Briar Rose returning from berry-picking. The fairies surprise her, and after finding out she met a stranger, they reveal her real identity (unaware that the stranger is the man she was betrothed to since birth). They remorsefully forbid her to see him again, much to her disappointment.
The fairies, back in their normal forms, take Aurora back to King Stefan's castle and take her to her boudoir where Flora makes a tiara for her. They leave a tearful Aurora in her boudoir alone, unaware that Aurora is still being cursed. They then find out she is about to touch the spindle on a spinning wheel (Maleficent in disguise, as in the princess's infancy, King Stefan ordered that all spinning wheels in the kingdom be burned), and they are too late and they find her "dead." They lay her on the bed and then put the kingdom to sleep. Flora then finds out from King Hubert (King Stefan's best friend and the father of Aurora's bethrothed) that Prince Phillip found the "peasant girl" once upon a dream, finding out that the stranger was, indeed, Prince Phillip. The fairies head back for the cottage, only to find out that Maleficent and her goons have captured the prince.
The fairies then go right to the Forbidden Mountain and sneak into the dungeon to free Phillip. Before he leaves, Flora uses magic to give him a sword and shield, and they escape, only for Diablo to warn the goons of the escape, and Flora uses her magic to turn the boulders, arrows and acid respectively into bubbles, flowers and a rainbow, and to help him escape from falling when the drawbridge door closes, but Merryweather chases after Diablo to turn him into stone. All three fairies then catch up to keep the forest of thorns from interfering with Phillip's escape. When Maleficent becomes a dragon, all three fairies put their magic into Phillip's sword so that Maleficent will die when he throws the sword at her. They then lead Phillip to the tower and rejoice when Aurora awakens. They are then seen on the balcony, watching, as Fauna cries happy tears while Flora and Merryweather fight again over the color of Aurora's dress with their magic.
The Three Fairies appear in the 2014 live-action film under different names and are referred to as the "Flower Pixies". Knotgrass (Flora's counterpart) was played by Imelda Staunton, Thistlewit (Fauna's counterpart) by Juno Temple, and Flittle (Merryweather's counterpart) by Lesley Manville. Though not outright vilifying them like King Stefan, this film portrays these characters in a rather unpleasant light compared to the clearly good original versions.
They first appear when they tell Maleficent (as a child) that a human went into the moors. This human turns out to be a child named Stefan (who would later become King Stefan), an orphaned boy and he quickly becomes Maleficent's best friend and later lover.
Later, they make another appearance when they grant the infant Aurora with magical gifts but when Maleficent places a curse on the young princess, they take her into hiding and raise her as their niece. They claim they are very good with children but it turns out they are incapable of looking after a child so while they struggle living like humans, Maleficent secretly cares for the princess from a distance and through Diaval while at the same time, pranks the trio just to kill her boredom.
Later, after King Stefan is defeated, the Flower Pixies appear at Aurora's coronation, when they give Maleficent the golden crown before Maleficent puts the crown on Aurora and crowns her to be the new queen of the two kingdoms.

In Sleeping Beauty, Flora, Fauna and Merryweather are the true three protagonists of the film, because Aurora (the film's protagonist among many fans) has little screen time and speaks only 18 lines, thus making her the deuteragonist, while the three good fairies (and Merryweather in particular) are shown to openly face the villain, Maleficent, thus making them the real protagonists.
Verna Felton, who voiced Flora, also voiced Queen Leah in the film, and previously voiced the Fairy Godmother in Cinderella and Aunt Sarah in Lady and the Tramp. Barbara Luddy, who voiced Merryweather, previously voiced Lady in Lady and the Tramp.
