Fox 3rd year middle schooler, female. She's pretty, but... not as pretty as the female members of the Quack Squad. She pretends to like exercising. She is absolutely terrible at sports. She's not very good at studying either. She is secretly watching for a chance to steal Lee Pingu, Tako's boyfriend. She has fought with Tako many times after getting caught flirting with Lee Pingu. Fox has a cute face so she's popular with 1st and 2nd graders, but among 3rd graders, she's rumored to be a 'sly fox' and is someone to avoid. Likes: Quack, Chester, Somyeol Likes very much: Lee Pingu!!!! Dislikes: Wolf, Tako (She clings to the Quack Squad members. She does it to the girls too, but it's an act to pretend she's close with them in front of the boys.)

Wolf 3rd year middle schooler, male. Unappealing appearance. Not handsome, just an average-looking person. He hits on Tako, Gomsung, and all the pretty girls. He is even worse with Tako.
