The Glass Cat

The Glass Cat (also known as Bungle) is a fictional character from the Land of Oz books by L. Frank Baum. She first appeared in "The Patchwork Girl of Oz".

The Cat's body is made entirely of clear glass, with a blood-red ruby stone in her chest for a heart, and several bright pink marbles in her head for brains. She was made and brought to life by Dr. Pipt and his Powder of Life, for the specific purpose of catching mice for his wife. But the Glass Cat turned out to be exceptionally vain, and unwilling to do any work.

It was quickly reasoned that it was Bungle's pink brains that had made her so conceited, and the Wizard of Oz eventually replaced them with clear ones to make her more agreeable. After her adventures with Ojo the Lucky and The Patchwork Girl, the Cat ended up being a pet of Princess Ozma in the Emerald City.
