- "Crazy kids with your long hair and your Baroque music..."
Mort was a gravedigger living in Mort's Shack in the Blood Island Cemetery. He owned a dog called Old Blind Pew. He claimed he was a vegan and was against ehe exploitation of animals. He was also a horror fan and budding horror novelist, having written the first part of horror trilogy called The Grog that Drank People. He claimed that some crazy kids often made him pranks, tralking to him through the crack opening into the Goodsoup Family Crypt. He also was a target of The Voodoo Kids for their Paper Voodoo Dolls. While in the Voodoo 'n' Things, Guybrush pulled a pin from his paper voodoo doll relieving from the pain. He also could (unwittingly believing the doll to be just a toy) torture the gravedigger by using the Pin, the Ember on a Stick, and the Bread Knife, and also scratch his back by using Murray's arm.
Later he were telling a joke to Griswold Goodsoup and buried Guybrush in the coffin in the Blood Island Municipal Housing for the Deceased believing him to be dead (though Guybrush was just unconscious from spiking grog with The Head-B-Clear). He does this again later but this time because Guybrush convinced Griswold he was a member of the Goodsoup family, he gets buried in The Goodsoup Crypt instead. When Guybrush talks to him through a crack in the crypt leading to his hut, he refused to believe that Guybrush was locked in the crypt and thought that he is one of the local punks that pranked him, therefore refused to let him out of the crypt. Being into horror novels Guybrush tried to scare him into believing he is a ghost haunting the crypt. He does succeed with help from Murray and making a very convincing shadow puppet on Mort's wall. Frightened, Mort opened the crypt and before going away begs "the ghost" to leave him in peace.

The strategy guide mistakenly says that Guybrush is a tricky ghost until he is scared by Murray. In the game, Mort thinks that Guybrush is a prankster kid, and starts believing he is a wimpy ghost when he uses the lantern.
