Grimalkin (also called "Malky", or Shadowpuppet) is a cat who is apparently made from glass. He served as Elphaba Thropp's pet while she stayed in the Emerald City.

He later appeared in A Lion Among Men, where he is found by Brrr in Shiz and taken up as his pet. However, by the end of the novel, the Clock of the Time Dragon reveals that he was actually a cat hired by the Wizard's government to spy on Elphaba and played a small role in Fiyero's death. He is imprisoned in the Grimmerie by Yackle when she reenters the book.



  • It is possible that Grimalkin is based on Bungle, a glass cat who made its debut in seventh book of the original Oz series; The Patchwork Girl of Oz.
