Ghosts were special Varmints that were released during the Haunted Halloween Extravaganza. They appeared when normal living varmints are clobbered. Ghosts could be killed by using the Ghost Cannon, provided that there was 1 Fire in the inventory. They could also be clobbered. It was possible to have both the ghost and the normal living types of varmint on your Homestead at the same time. After the Haunted Halloween Extravaganza ended, they had a 1% chance of appearing.
