The Wrong Shirt (Opposites) Blue's Clues : Season 3 Episode 21

When we come in, we find that there's something very different about Steve's clothing - he's wearing a button-down shirt that looks like his normal pants and striped pants that look like his normal shirt. Mr. Salt and Mrs. Pepper explain what opposites are and Steve seems to like the idea. We learn more about opposites when a guy named Bob skiddoos out a picture frame into the Blue's Clues house to deliver something to Steve. His presence often causes things to turn opposite. He has a magic ability that can fix it, but it's up to us to first find the things that are opposite so that we can tell him to fix them. Later, we skiddoo into a book where we help out two sisters that like opposite things to make their favorite places.
