This alter ego is introduced during a storyline in which Peppermint Patty invites Snoopy (believing him to be a "funny-looking" boy with a big nose) to a "turn-out" dance at her school. Snoopy dresses formally and is excited to accompany Peppermint Patty. However, she angrily punches a boy who insults Snoopy's appearance and is kicked out by a chaperon. Upon apologizing to Snoopy, he kisses her and reminds her that he had bitten the chaperon.
