Murray is a human that uses his "Murray the Monster" act to sell merchandise of the character. He dresses up as the monster and commercializes the products, including plush dolls and various toys of Murray the Monster.
After catching the interest of the real monsters, he is later approached by Ickis, Oblina, and Krumm, who proceed to frighten him by tapping into his brain via a lobotomy-style implementation and this forces him to acquire a fear of monsters and stops him from his charade of salesmanship.
Murray wears a purple outfit for his "Murray the Monster" attire. The outfit is rather unique, having a fish-like appearance with webbed hands. The outfit also has a bow-tie, numerous legs, and a tail. His lips are blue and he has golden eyes as well as bumps on his head. When not in the monster getup, Murray has a thin moustache and brown hair.
- Murray has a simple catch-phrase: "Uh-Huh! Uh-Huh!" He says this in both a positive and joyous way when attempting to sell products and with a sad undertone when admitting to something negative.
