Ghostly Terror

"'If all nature is gone on Earth, does that mean the ghost of every animal lives on? Works better with Ghostly Pumpkins on your base.'"

Overview
The Ghostly Terror is a Supreme tier Mine, which gets better the more Ghostly Pumpkins are placed down. It could have been obtained from Boxes during the Halloween Event. The ore value starts off at a high $250,000, and with each Ghostly Pumpkin placed on your base, it goes up by $2,500 ore value. This has no cap.
