Looney Tunes Baseball Card 225

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. 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.

After the original Looney Tunes shorts, Junior would show up sporadically in later years. In the 1990s animated series Sylvester and Tweety Mysteries, Sylvester has a flashback to his childhood in the episode "A Mynah Problem"; in the flashback sequence, as with Tweet Dreams, Sylvester resembled his son physically.
