Iggy was one of gangster Mickey Malone's dogs. He never makes an in-game appearance, although one of the four "ghost dogs" in Ghost Dogs of Moon Lake was supposed to represent his ghost.
Iggy was born on August 16, 1923. His owner, Mickey Malone, took care of Iggy until he was arrested on January 29, 1932. Following Malone's instructions, his friend Willy had Iggy's gravestone inscribed saying that he died on the date that Malone was arrested. However, according to Willy's journal, Iggy lived on, being cared for by Willy after Malone was arrested. The circumstances of his death are unknown.
When he was alive, Iggy was very lazy. He ran around and barked less than Xander, Lucy, and Vitus. Iggy's favorite spot to rest was the porch. Vivian Whitmore, Malone's former girlfriend said she liked Iggy more than the others.
