Periwinkle is a lilac tabby kitten, a light shade of periwinkle with purple triangles on his forehead. He has triangles on his back. His nose is pink. Periwinkle has a long tail and four paws. Each paw has four toes. His right front paw is periwinkle and the others aren't.
Periwinkle is one of the few major characters 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 appear in an episode 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.
Some promotional images and clip art show him with a dark patch on his right front paw instead of his left.
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.
