This study examined Wandeugi by Kim Ryeo-ryeong in terms of multicultural family, growing process of the subject, and patterns of teachers who practice multicultural education based on Bakhtin`s Carnival Theory. Wandeugi is a story about the growth of Wandeugi who comes from a minority and multicultural family that our society tries to cover up. He is the son of a minority individual that is a midget and the son of a Vietnamese mother in an international marriage. Compared to his dismal family background, the entire work is rich in "comic" elements in the atmosphere. And the driving force behind such a humorous atmosphere is Bakhtin`s Carnival Theory. Addressing race, social class, and gender liberation, the theory creates a venue for festivals, whose moods are usually represented by curses, vulgar words, excretion, maximization of the lower body, and food. Those elements are transformed in Wandeugi. The "carnival-like" characteristics that mature a festive atmosphere are altered, whose cases include curses and vulgar words in the talks between Wandeugi and his homeroom teacher, the foods made by his mother who left home on her return, his "sweat" when he was committed to boxing, and his midget father and stuttering Nam Min-gu absorbed in "dance." In an unfortunate family environment, Wandeugi creates opportunities to communicate with his homeroom teacher, mother, and neighbors through carnivals and exhibits the possibility of overcoming his unhappy life.
