The company that represents the Diary of a Wimpy Kid brand recently won a temporary restraining order against the publisher of two Wimpy Kid-parodying graphic novels: the "Wimpy Zombie" series by Fred Perry and David Hutchison. According to Publishers Weekly, the zombie books strongly resemble the originals, and their publishers didn't include a "parody" stamp.
