Ghosts

Ghosts are the fourth creature that can be unlocked outside. Tombstones are required to buy more ghosts (ie. you can't buy 1000 Ghosts until you have 1050 tombstones). Once ??? tombstones and ??? ghosts are acquired ghosts come out of the tombstones. Ghosts can be captured by clicking them with the Ghost Trap. Ghosts appear in a variety of colors which give different prizes for being captured. After ??? ghosts are purchased, Simple Simon can be played.
