 In a parody of Harry Potter , Bart and Lisa go to the “ Springwart ’ s School of Magicry ” in which young boys and girls are trained in the art of witchcraft , such as turning frogs into princes , with Lisa 's turning into a perfect British one while Bart 's results in a freakish , vomiting hybrid begging only for death . Lord Montymort notices Lisa ’ s spells and he and his snake sidekick , Slithers decide to capture Lisa in order to increase his power . Montymort looks for someone to assist him and chooses Bart , who agrees to Montymort ’ s proposal . On the night of the magic recital at Springwart ’ s School of Magicry , Lisa attempts a “ levitating dragon trick ” on an gigantic dragon that is released onto the stage . Lisa is shocked to find that her spell will not work , and then notices that Bart has replaced her wand with a Twizzler . The dragon morphs into a giant Montymort who captures Lisa and begins sucking up her power . Bart casts a spell ( to destroy the evil one ) against Montymort , but is struck by lightning . In a last @-@ ditch effort , Bart charges at Montymort and stabs him in the shin with his magic wand . Montymort dies ( as his shin was the source of all his magic ) and is eaten by a crying Slithers . Bart and Lisa walk away , trying to forget everything that happened ( unaware that the leprechaun from the first story is right behind him ) .
