Periwinkle is one of the few characters that is not a minor character to debut after the second season.
In "Blue's Big Musical Movie", Periwinkle thought the group inside the house were doing a magic show when they were really doing a music show. But because the Blue's Clues group needed more time to get ready backstage, Periwinkle did his magic show to entertain the audience.
Periwinkle happened to be the first character to be introduced a few times.
Sidetable Drawer tells Periwinkle that she wanted to sing in the show but never told Steve she wanted to. While Periwinkle had a similar response, Steve never got to see any of his magic tricks.
He only appeared in only a few episodes with Sidetable Drawer saying "Blue's Clues, I'm so excited" because most episodes with Sidetable Drawer saying "Blue's Clues, I'm so excited" were before Periwinkle's debut.
