Bad Mojo is an adventure video game by Pulse Entertainment, released in 1996. The player is cast as Roger Samms, an entomologist planning to embezzle money from a research grant to escape his sordid life above an abandoned bar. An accident with his mother's enchanted locket unleashes the bad mojo, turning him into a cockroach. The storyline in Bad Mojo is loosely based on Franz Kafka's 1915 novella The Metamorphosis. In the game, the cat's name is Franz and the main character Roger Samms is an imperfect anagram of the lead character in Metamorphosis (Gregor Samsa). The gameplay consists of guiding the cockroach through a series of puzzles.
