Biography
Muffin was brought along to Packanack Logde Counselor Training Center by her owner, Terry McCarthy in 1984. Shortly after arriving at the Training Center, Muffin encountered backwoods killer named Jason Voorhees while exploring in the woods. Later that day, Sandra Dier and Jeff Dunsberry found the carcass of a dog that looked suspiciously like Muffin, although this was not, because Muffin is showed to be alive at the very end of the film, meaning that the dog being found by both Sandra and Jeff was not their beloved Muffin. That night, after surviving Jason's first killing spree, Ginny Field had been reunited with Muffin, though this is highly suggested to be a dream sequence. It is unknown whether Muffin survived or not.
