Abby Cadabby Abby Cadabby is a three - year - old fairy - in - training who lives on Sesame Street . She made her debut in 2006 , in the first episode of " Sesame Street " ’ s 37th season , when she moved into the neighborhood and met some of the Street ' s residents . On the day of her debut , her wand broke ; Big Bird told her to take her wand to the Fix - It Shop where Maria would fix it . Starting in the 40th season , she received her own CGI - animated segment , " Abby ' s Flying Fairy School " . Her name is a play on the magic word " Abracadabra " . Abby ' s magical powers are limited to popping in and out of thin air , floating when she ' s happy , and turning things into pumpkins . Although familiar with the world of fairy tales , Abby is astounded by such basic learning skills as drawing letters or counting , prompting her catchphrase " That ' s so magic ( al ) ! " She frequently uses her wand cell phone to call her mommy . When she ' s asked to return home , she says that she ' s " gotta poof " or " disappear . " She can speak a language called Dragonfly and is teaching Rosita the language , while Rosita teaches her Spanish . Along with Baby Bear , Abby begins attending school in a 2006 episode at the Storybook Community School , where Mrs . Goose is the teacher and other fairy tale characters like Hansel and Gretel are her classmates . Abby ' s parents are divorce d and she spends part of her time living with her mommy and part of it living with her daddy . In season 47 , Abby ' s mom gets married again and Abby not only gets a new stepdad , but also a step - brother too , Rudy , a 3 year old monster who has a habit of using her wand without her permission . Tony Geiss conceptualized Abby as a way to simultaneously introduce a major female character to the show and add someone from a different culture , without " having consciously to introduce somebody from Indonesia or India . " Abby ' s design is an intentional departure from the typical Muppet look because she ' s not originally from Sesame Street . The implication is that the fairies in her old neighborhood look like her . Carrara ' s audition with Abby was a 15 - minute long improv with Fran Brill as Zoe , about fairy castles . Abby ' s likeness has been adapted for a 43 - foot balloon which premiered in the 2007 Macy ' s Thanksgiving Day Parade , a full - body costume character for stage appearances and a number of merchandise items . In 2008 , Abby was added to the cast of " Plaza Sésamo " , the Mexican co - production of " Sesame Street " , appearing in new segments where she tries to perform magic tricks with various ordinary objects .
