Sammun-Mak was first mentioned in The Devi'ls Playhouse Episode 2: The Tomb of Sammun-Mak. During this episode Sam and Max's grandparents, Sammus and Maximus, are going through an adventure of trying to remove the Devil's Toybox from Sammun-Mak's tomb. As the story goes, before Sammun-Mak became a pharaoh, the Devil's Toybox fell from the heavens and landed right before Sammun-Mak. Summun-Mak was the only being capable of using these toys for his own use. His use of psychic abilities eventually made him a pharaoh. At the time of Sammun-Mak's reign, he ruled largely over a moleman/ molewoman population. Therefore, after Sammun-Mak's untimely death, the molemen took it upon themselves to guard his tomb and his Devil's Toybox.
In Episode 3: They Stole Max's Brain!, Sam has to use Sammun-Mak's preserved brain to bring Max's lifeless body back to life. Even though Sammun-Mak was in rabbit-form, he was still able to make use of the powers of the Devil's Toybox. Together, Sam and Sammun-Mak were able to steal back Max's brain, however, Sammun-Mak rediscovered The Devil's Toybox and transformed reality so that he was pharaoh of the United States of America.
