My Little Pony: Friendship is Magic

When Fluttershy asks Spike to watch Angel in exchange for a gem, Spike eagerly agrees to take care of her pet. But finds himself in over his head after he convinces all of her friends to leave him in charge of their critters as well.

The Apple family reunion is approaching and Applejack offers to take over the event's organisation from Granny Smith after going through photos of past reunions. Though Applejack's planned activities are in the spirit of the reunion, the events are long and rigorous, leaving all the guests exhausted. When a wild hay ride destroys a barn, Applejack realises that she has focused too hard on the event planning and not on the real purpose of the reunion: to be with friends and family. She gets an idea and has everyone join in to help rebuild the barn, which everyone is happy to help contribute to, thus making the reconstruction a memorable event of the reunion.

When Applejack saves Spike from a timberwolf attack in the Everfree Forest, he insists on helping her around the farm in order to repay the life debt he feels he owes her. His efforts only make trouble for her and the other ponies, and they set up a fake timberwolf attack for Spike so that he can save Applejack from, thus making him feel satisfied with his debt. Their ruse draws a pack of real timberwolves, which Applejack easily crushes, but the pieces form into a single giant beast and she gets caught in a rockslide. Spike causes the timberwolf to fall apart by throwing a rock down its throat, and frees Applejack. The two decide not to worry about repaying favours done for each other in the future.

Princess Celestia tasks the ponies with reforming the mischievous spirit Discord, believing Fluttershy will know how to do it best. While her friends are incredulous that Discord can be reformed, Fluttershy remains steadfast and tries to be Discord's friend. When the others find that Discord has created mischief behind their backs, they demand Fluttershy use her Element of Harmony to return him to stone, but Fluttershy stands firm, and promises not to use her Element against him as a sign of their newfound friendship. But when Discord's actions get out of hand, she angrily walks away, still refusing to use her Element against him, but also ending her friendship with him. Never having had a friend before in his life, Discord is stricken by genuine sorrow as he realises that he truly does value Fluttershy's friendship and does not want to lose it. With this revelation, Discord reverts his chaos and voluntarily offers to use his magic mostly for good.

Princess Cadance asks Twilight Sparkle and her friends to help prepare the Crystal Empire for the arrival of the games inspector Ms. Harshwhinny, hoping to have the city host the next Equestria Games. With the inspector due to arrive earlier than expected, Cadance must spend time preparing herself styling her ceremonial headdress with Rarity's help, and asks the other five to greet and give a tour to the inspector. Twilight and her friends mistake a tourist as the inspector and give her a grand tour, while the real Harshwhinny finds herself subject to a number of accidental missteps. By the time Twilight realises their error, Harshwhinny has met with the tourist and learns of how great a time she had, and despite her own misfortunes, she announces the Crystal Empire as the next host city.

Princess Celestia gives Twilight Sparkle the notebook of Star Swirl the Bearded, which contains a final, unfinished spell that she thinks Twilight can complete. When Twilight evokes it, it causes her friends—through the Elements of Harmony—to have their cutie marks and respective destinies switched, resulting in disasters around Ponyville. Twilight finds a means to convince each of her friends of their proper place with the aid of the Elements, restoring her friends to normal, and is able to complete Star Swirl's spell, accounting for her friendships. When she does so, Twilight is teleported by the Elements to an ethereal place, where Princess Celestia congratulates her on completing her journey, and helps her transform into an alicorn and crowns her as a new princess. Twilight's ascension is celebrated by her friends and across Equestria.
