Happy

Happy is one of the seven dwarfs and an ally to Snow White. He is also a member of The Council of Sidekicks.

Before Auradon
Happy is first introduced, with his seven companions, at the Dwarfs' Mine. He, Bashful, Sneezy, and Grumpy dig to unearth diamonds from the tunnels. The diamonds are taken by Sleepy to Doc, who puts the valuable diamonds in bags to keep and discards the worthless diamonds for Dopey to sweep away. Doc is the first to hear the alarm and alerts the other dwarfs that it is time for them to go home. Happy walks behind Grumpy as the dwarfs sing "Heigh-Ho".

When the seven dwarfs reach their cottage, they think that a monster has taken up residence in their house. They sneak into the cottage and search the room. At one point, Dopey and Happy see something cooking on the fire. Happy is about to try it when Grumpy stops him, suspecting that it is "witch's brew". The dwarfs note that the cottage has been cleaned. They decide that whatever is in the cottage is upstairs, and Doc declares that one of them must go upstairs to chase it out of the house. Dopey is elected, and Doc, his hand shaking, gives Dopey the candle. Dopey is so terrified upon entering the bedroom that, when he hears a noise coming from the beds, he screams and rushes downstairs.

The other dwarfs think that he is the monster and rush outside, locking the door. Dopey falls into the kitchen and emerges from the cottage covered in pots and pans. When the other dwarfs see him they still think that he is the monster, and start hitting him. When they realize that it is Dopey, they decide that they must get rid of the monster once and for all, and enter the bedroom. They are about to strike whatever is sleeping in their beds when they realize that it is the princess, Snow White. Grumpy begins to complain, and Doc attempts to silence him, but Snow White is woken up. She manages to match the name at the foot of each bed to the correct dwarf. Happy is the fifth dwarf identified and actually introduces both himself and Dopey.

Eventually, it is agreed that Snow White will clean and cook for the dwarfs if she is allowed to stay. She prepares soup for them but demands that they wash first. The dwarfs reluctantly march outside. Here, the dwarfs, led by Doc, wash. When Sneezy dips his finger in the water, he blubbers, shocking Happy and the other dwarfs except for Grumpy, while singing "Bluddle-Uddle-Um-Dum (The Dwarfs' Washing Song)". Grumpy refuses to wash, but the other dwarfs, led by Doc, manage to drag him to the water and wash him thoroughly, and Happy, of course, places a wreath on Grumpy's bald head, and kisses and pats it tenderly. Later that evening, after supper, the seven dwarfs entertain Snow White with "The Silly Song"; to begin with, Happy sings a verse to Snow White, and appears to lead the yodeling. He later plays the drums while Dopey and Sneezy dance with Snow White.

After they finish the song, the dwarfs listen to Snow White sing "Some Day My Prince Will Come", which sends every dwarf, except the stubborn Grumpy, into a dream-like state. Doc declares that Snow White will sleep in the bedroom upstairs, and the dwarfs must sleep downstairs. Happy sleep in a cupboard and his snoring sends it to shut and open.

The next morning, each dwarf leaves and gets kissed by Snow White. (For some reason, though, Happy was never shown being kissed on the forehead, nor is he present during the scene.) While the dwarfs head to the mine, the Queen, as the Witch, makes her way to the cottage, knowing that only Snow White will be at home. Upon her arrival at the cottage, the animals sense danger and, after attempting to drive her away, rush to the mine to fetch the dwarfs. When they discover that the Queen has found Snow White, the dwarfs rush home to find that the Witch has succeeded in poisoning the princess and is about to leave. Enraged, Happy, alongside the other dwarfs, chases the Witch into the mountains, and she reaches a cliff. She attempts to crush the dwarfs with a boulder, but a flash of lightning causes her to fall from the cliff and be crushed by the boulder herself.

The seven dwarfs mourn Snow White's death; Happy, like everyone else, is devastated, and tears stream down his face as he cries silently. The dwarfs find her to be so beautiful, even in death, that they fashion a coffin from glass and place her inside. The Prince arrives, and the dwarfs part so that he can approach Snow White. He kisses her, breaking the spell of the Sleeping Death, and the dwarfs cheer. Before Snow White leaves with the Prince, she kisses each dwarf on the forehead (Happy was fifth).

Trivia

 * According to him, Doug's father (Dopey) is unable to talk only because he never attempted to.
 * In Descendants 2, it's mentioned that Happy has a son, but he is not as happy as his father since Doug considers him as a dark streak.
