Jumper was Johnny Ghost's pet dog and the first PIE mascot from his childhood. Johnny Toast knew him as Spot because "he was always spot on". He was killed in a hit-and-run accident some time before 2014 while out with Ghost, something that Ghost has never completely recovered from. Ghost and Toast encountered a desiccated Doberman Pinscher corpse in the Black Diamond Facility that heavily resembled Spot.
- In 2016, Johnny Ghost recalled owning a dog called Quasar as a child. Quasar disappeared in 1992.
