Grommetik is a robotic Tik-Tok creature in the Gregory Maguire novel Wicked. From the description in the novel, he bears a resemblance to the character Tik-Tok from L. Frank Baum's original Oz Books. Grommetik is the servant of Madame Morrible, the headmistress of Crage Hall at Shiz University.
Grommetik is supposedly the murderer of an Animal professor at Shiz, Doctor Dillamond, though was probably acting under Madame Morrible's orders. At the end of the novel, it is written that Grommetik is planning a class revolution for all tik-toks, centred in the building which once served as the Philosophy Club..
