Often, Sylvester and Junior's shorts would feature Sylvester trying to capture Hippety Hopper, a baby kangaroo, to prove a point to his son. Each attempt at capture, of course, failed miserably, owing to Sylvester's invariably mistaking the kangaroo for a "giant mouse", and as such being taken completely by surprise by the kangaroo's athletic prowess, with Sylvester losing every fight, often in spectacularly humiliating fashion. In one particular ship based short Junior was able to outdo his father by capturing Hippety, playing on Hippety's playful nature. Though "Tweet Dreams" was the only pairing of Junior and Tweety in the "Looney Tunes" shorts, it was not a direct one; Junior basically served as a flashback image of Sylvester himself when he was his son's age.
