After 100 days on the high seas, Roger crashlanded on a deserted but lush island. Not able to free his ship, he decided to settle down here. This descision turned out to be great and he became a really Jolly Roger.
After some time, word of the lush island and its happy inhabitant spread fast and many people also wanted a slice of happyness. So the only reasonable conclusion for roger was to build a park, get rich and put his post mortem portrait on a flag.
