"Pinkie Pride" is the twelfth episode of the fourth season of the animated television series My Little Pony: Friendship Is Magic, and the seventy-seventh episode of the series overall. It was directed by Jayson Thiessen, co-directed by Jim Miller, and its screenplay was written by Amy Keating Rogers from a story by Thiessen. It was produced by Sarah Wall and Devon Cody. The episode centers on Pinkie Pie (voiced by Andrea Libman), whose plans to organize a birthday party for Rainbow Dash (Ashleigh Ball) are interrupted by a similarly energetic pony, Cheese Sandwich ("Weird Al" Yankovic), leading Pinkie Pie to defend her pride as a party planner in a "goof-off". Yankovic's involvement in the episode was the result of interactions on Twitter between him and Jayson Thiessen. Aired on February 1, 2014, on the Hub Network, "Pinkie Pride" was viewed by 459,000 people and garnered acclaim from critics, who praised Pinkie Pie and Cheese Sandwich's characterizations. Plot As he oversees an extravagant party he has thrown in Appleloosa, party planner Cheese Sandwich senses a "doozy" of a party being thrown in Ponyville, where Pinkie Pie is organizing her friend Rainbow Dash a party, celebrating both the latter's birthday and anniversary of her move to Ponyville. Pinkie promises to throw Rainbow Dash the best "birthiversary" party ever when Cheese appears and introduces himself as the premier party planner in Equestria. Though initially delighted to meet a party planner like herself, Pinkie is upset as Cheese enraptures the townsfolk with his party-throwing skills, causing her friends to desert her for Cheese's party. Cheese begins building a massive set for Rainbow Dash's party, while almost all help him build it. Doubting her own partying skills, Pinkie attempts several odd-end jobs around Ponyville that fail. She returns home dejected and begins to put her party supplies away before looking through framed pictures showing various parties she has thrown in the past. With renewed confidence, Pinkie challenges Cheese to a goofing showdown ("goof-off"), declaring the winner will be dubbed the single best party planner and headline Rainbow Dash's party. Cheese accepts and Rainbow Dash becomes the judge of the competition. The two try to outdo each other with increasingly silly and elaborate performances until Pinkie accidentally drops a giant piñata on top of Rainbow Dash. Pinkie realizes her pride has gotten in the way of Rainbow Dash's party and forfeits the goof-off to Cheese. Pinkie
