Biography[]
Elvis was one of two pet rats that Michael Myers owned when he was a young boy of ten. On Halloween 1990, Michael watched Elvis, held him in his hands and killed him with a small knife.
To avoid getting caught, Michael flushed Elvis, washed his hands and the blood on the blade and told his mother that Elvis had died. Deborah told him that she would get him another pet rat.
