Glass Cat
Bungle, the Glass Cat is a character in the Oz books of L. Frank Baum.[1] More prominently featured in Baum's latter books, the Glass Cat often is depicted as using her unique characteristics to the benefit of her companions. Bungle was not well-liked by other inhabitants of Oz due to her self-absorption, but she is suggested to be less uncaring than she appears. Like other Oz characters, Bungle serves to blur the line between person and animal, object and living being, having been described as more intelligent than a typical cat with brains above her station in life. [2][3]
Development
Baum was unusual in creating a character that is transparent but visible. In a story published twelve years prior to Bungle's debut, American Fairy Tales, Baum magically animates a similar spun-glass animal, although the dog is not transparent but pink, with a blue ribbon around its neck and shiny black glass eyes.[4]
Bungle along with the other new characters in The Patchwork Girl of Oz represented a shift away from the static cast of characters featured in previous Oz books. However, upon encountering the previous cast of Baum's Oz, Bungle and the Woozy are removed from the journey to be replaced by Dorothy and the Scarecrow.[5]
Characteristics
The Glass Cat is transparent, except for her hard blood-red ruby heart, two large emeralds for eyes, and her bright pink brains, which look rather like a collection of marbles and can be seen working in the cat's head. She has a tail of spun-glass.

Despite being made of glass and fearing being broken, the Cat is shown to be virtually invulnerable to harm, which is a great advantage in its various adventures. For instance, it is shown to be immune to the violent attacks of the various beasts of Oz.
In personality, Bungle is almost stereotypically catlike—cool and reserved and aloof as well as vain. The cat "is so determined not to show emotion that when implored to bring help she sets off very slowly and runs only when out of sight."[6][7]
Through its incessant prowling throughout the Land of Oz, however, the Glass Cat has acquired intimate knowledge of its complex terrain; and it is generally willing to exploit this knowledge to the benefit of Dorothy and her friends.
History
Bungle first appears in The Patchwork Girl of Oz, the seventh of Baum's fourteen Oz books. The magician Dr. Pipt tests his Powder of Life by animating an ornamental glass cat figurine, for the specific purpose of catching mice for his wife Margolotte. But the Glass Cat turns out to be exceptionally vain, and unwilling to do any work. Margolotte names it Bungle, in reference to the magician's failure to create a useful mouser.
Accompanying Ojo on his journey, the Cat aids the boy by leading him to shelter in pitch darkness using her night vision. Once they reach the Emerald City, she opts to stay behind for fear of being shattered.
During her stay, it was quickly reasoned that it was Bungle's pink brains that had made her so conceited, and at the end of The Patchwork Girl of Oz, the Wizard of Oz replaced them with clear ones to make her more agreeable. After her adventures in that book with Ojo the Lucky and the Patchwork Girl, the Cat ended up being a pet of Princess Ozma in the Emerald City. But in The Magic of Oz, a few books later, her brains were pink again and her original personality had returned, including her catch phrase about the superiority of her brains: "They're pink, and you can see 'em work."
At the end of the story, the Glass Cat is admired by the titular monarch, in Rinkitink of Oz.
In The Magic of Oz, the Glass Cat guides the rescue party that saves Trot and Cap'n Bill from entrapment on the Magic Isle.
When Button Bright got lost in an area of Oz inhabited by dangerous animals, during the events of Glinda of Oz, the Glass Cat retrieves him, relying on her invulnerability to protect her.
Interpretation and Analysis
In the hierarchy of different castes featured in Baum's Oz, the Glass Cat can be considered an "inorganic inanimate" as her constituent material was never alive and unmoving in nature. This is in contrast to creatures like the Sawhorse that were made of material that was once alive.[2]
Andrew Karp argues that Bungle's mockery of the Patchwork Girl's characteristics while remaining prideful of her own unusual appearance, is intended to highlight the absurdity of an individual or insular group imposing standards of conduct and appearance on others. [8]
Dina Schiff Massachi notes that the Glass Cat regrets having been brought to life, that despite wanting to be more than a servant, by ignoring her purpose of catching mice she takes on the life of a mere ornament. Due to her self-prescribed purpose, she attempts to reinforce her identity through narcissistic obsession. Thus, her brains, the source of the vanity, are useless by the standards of Oz and must be replaced for her to be socially acceptable. In contrast to the Patchwork Girl who is emancipated while maintaining her eccentricities, Bungle elevates herself to a prize collectable. [9]
