What is the name of the character who enters a castle and finds a giant birdcage?
The story begins with a farm mother scolding Jack for trading his cow for five seemingly worthless beans. The beans are thrown out a window and land under Sylvester's cat bed while the lazy cat is taking a "catnap". Instantly, the beans sprout into a giant beanstalk that reaches into the heavens, taking the still sleeping Sylvester with it. The puddy tat awakens and is startled at how everything seemingly grew overnight. Eventually, he walks inside a castle and instantly spots a giant birdcage (with a giant Tweety singing inside). Sylvester opens the cage and chases what he says are "acres and acres of Tweety Bird." However, Tweety's master comes into the room; after Sylvester hides, the master puts Tweety back in his cage and hangs it on a high ceiling; that way, he will not get into any mischief while he is gone.
Sylvester makes several attempts to get at Tweety, having to overcome both the cage being on the ceiling and dodging a giant bulldog who is trying to chase the cat away. Each of Sylvester's attempts to get the bird ends unsuccessfully; several times, he is barely able to get away from the bulldog. At one point, he encounters a real giant mouse, only to have both of them get scared of each other and run away in opposite directions.
