"Hildyrella" is an episode that premiered on November 16, 2014 with "The Enchanted Shoes" on Disney XD. Before it was officially announced, it was confirmed by Shea Fontana on her website. Along with "The Enchanted Shoes", the premiere doesn't air in its entirety (see trivia below).
It is the thirty-second episode in the series.
Hildy faces off against her arch-nemesis Snazzy Shazam in the Ultimate Supreme Sorceress Pageant.
At the Glooms' manor, Hildy is preparing for her entry into the Ultimate Supreme Sorceress Pageant. As she flies to the event with Grim while putting on makeup, she is about to collide with a bird. She avoids it, but she fell into a pig pen full of mud; her shoes are then digested by the pig. Grim suggested to Hildy that she should wish for a fairy godmother. The Fairy Godmother appears, and Hildy has to keep her sassy behavior in check if she wants to go to the pageant and win by midnight. Hildy eventually gets her wish, and along with a new dress she receives a squid coach with a cockroach servant and a new pair of shoes.
Meanwhile, the 7D answers the Bing-Bong Bell and reported at Delightful's castle for duty. The Queen participates in her roller derby team known as the Raging Regals (they're playing for the championship tonight) and her roller skates are missing. The dwarfs suspect that the Glooms are behind this since Delightful told them that the skates vanished as she opened its box. They followed the Glooms' trail and ended up at Shriek Auditorium where the pageant is being held; the 7D went in disguised to avoid detection from the evil witches and wizards while becoming the judges by accident. Starchbottom substituted for Delightful at the roller derby until she get her skates back.
One of the participants at the pageant is Hildy's rival, Snazzy Shazam. Later, a dance competition is being held during the pageant. Hildy takes the stage and dances, showing off what are actually Queen Delightful's roller skates. She then loses her balance and fell into the judges' table, revealing the 7D's disguises. As the dwarfs flee, Hildy casts a spell to turn them to Chihuahuas on her wand; the spell missed and instead hits the emcee, Snake Charming. The 7D then escaped the flying spells from the enemy wizards, reached the queen, and Delightful got her skates back and entered the derby.
At last, the pageant is about to crown its winner. The Fairy Godmother appears before the announcement is made; the clock strikes at midnight and Hildy is reverted back to being covered with mud from the pig pen. Despite not being in the pageant the Fairy Godmother is declared the winner while she flirts with Snake Charming. Back at the derby, Delightful and her team wins the championship.
