This Kassegat is long since dead, and hangs around in the corner of the Shadow Grove in the Petpet Park. She claims that there are many more of her kind about. She's good friends with Captain Arf, and keeps a skeleton key which is needed to open his treasure. Her body is buried in the Founder's Cemetery area.
There are a lot of bad rumours floating around about us ghosts. I assure you most of them are totally unjustified.
There are more ghosts here in Petpet Park that you might think.
The inscription on Opal's headstone reads, "Rest in Peace, Opal. You finally found a jewel more distant than yourself."
