Sofia The First Season 1 Episode 19 Princess Butterfly Episode Title:Princess Butterfly.Episode Description:Everybody at Royal Prep is looking forward to the All-Hallows Eve costume ball, where everyone gets to dress up in different costumes and attend a party, and nobody loves dressing up more than Amber, who has always won the costume contest held each time at the ball. However, this year the fairies decree that everyone must make their own costume, and Amber doesn't know how to. When she sees Sofia's beautiful swan costume, she gets jealous, and worried of her chances to win, deciding to borrow a magic spell from Cedric to create her costume. Cedric gives her some magic crystals that will conjure a beautiful butterfly costume, but his true intention is to steal Sofia's amulet. His crystals work on Amber during the ball, and she wins the contest yet again, only to find that she is unable to take it off and that the costume is real. Returning to Cedric, who had predicted this and done it on purpose, he promises an antidote, but one that needs Sofia's amulet. Knowing of how precious it is to her sister, Amber ponders for a day and is forced to wear it to school. After a few unsuccessful attempts to take Sofia's amulet, she confides in her sister about her predicament, and Sofia generously gives it to Amber. Just as she is about to take it, she rejects Sofia's amulet and decides to tell the fairies of her dishonest behaviour, only for Wormwood, Cedric's pet crow whom he had ordered to tail Amber, to steal it instead. A chase ensues throughout the Royal Prep campus, where Amber realises her butterfly wings can actually fly. After hitting down Wormwood and regaining the amulet, Amber comes clean to the fairies, who lift the spell. Amber promises to return the trophy to the school.
