Blue's Clues

We ring the doorbell and Steve opens the door, dressed up in a suphero outfit complete with cape. Some of the characters in the Blue's Clues house are pretending to be superheroes and he's "Stripe Man." We also meet up with Super Blue, who has the power of leaving clues and skiddooing, Clock Girl (Tickety) and Super Soap. (Slippery) We help Steve to realize that his superhero mask is right on his head and so he gives us our very own superhero name: The Incredibly Helpful Friend. Now that we're all together, we form the Thinking Squad. Using our superpowers, we help out with a number of problems. When we find some spilled milk, we help Steve to choose Super Soap as the best superhero to call on to clean up the mess. Mr. Salt has some juice pops that are going to be ready at 2 o'clock and so we call for Clock Girl's help to make sure that it's the right time. Then we use a very own skill to help Paprika to find her missing teddy bear so that she can have a nap. In the Blue Skiddoo segment, we meet up with Frank in Superheroville. Steve wonders why Frank doesn't have superhero name and it turns out that it's because Frank doesn't know what his Superpower is. We meet up with a couple of other members of Superheroville and Frank helps them with their problems. Fancy Dancer doesn't have anyone to dance with, so Frank agrees to dance with her. Then The Runner appears, but keeps falling down when she's trying to run. Frank has her tie her shoes and soon she's running again, as fast as the wind. We realize that Frank is great at making people feel better and so he becomes Cheerer-Upper, complete with his own superhero outfit.
