Hello man. To get easy pearls you can open up the console (to enable open go to "renpy"->"common"->"00console.rpy" and change config.console to "True). To open console, press Shift+O. To add a pearl, you type: inventory.add("pearl",<# of pearls>), and to add a pearl necklace, you can do inventory.add("pearl_necklace")
