Sassette Smurfling is one of the Smurflings who appeared in The Little Smurfs episode, she was created by Smurflings who had used the Smurfette creation from Gargamel who hates the Smurfs. She started as an minor villainess, but Papa Smurf manages to turn her into a real Smurf similiar that how Papa Smurf turns Smurfette into a Smurf.
She was the second female Smurf who was created by the same magic formula Gargamel had used to create Smurfette with, though the Smurflings who created her used a smaller amount of blue clay than what Gargamel used for Smurfette, resulting in a female Smurfling.
Her attitude is that of a tomboy Smurfling who likes to do things that her fellow male Smurflings do. Smurfette considers her a sister Smurf though, despite having a hard time understanding Sassette's interests at first. She does have a girly side however, as she likes dressing up and playing with her doll Smurfy Lou.
