Someone sent me a link to a page asking what a strange code in Paper Mario: Sticker Star was used for. Here's what I could find about this code: The code is XD3R-B8HH-9ZR2-FL16. It is found in World 5-1 (Shy Guy Jungle), in the trash heap. The code is the same every time, in every single copy of the game. When you find it, Mario reacts to it in the same way he would react to any useless piece of trash you can find in the trash heap. It is not used within the game itself. It resembles a serial key for a game or application. The code has been confirmed to not work on Steam, Club Nintendo, Wii U eShop, Wii Shop Channel, or 3DS eShop. Someone here appeared to have been investigating this code and another of the strange messages found in the trash heap, but nothing has been found since January. Unfortunately, I couldn't find anything on whether or not anyone has contacted Nintendo to ask about the code. I also couldn't find anything on whether or not anyone has tried the code in Desura or Origin. These could be a couple of things to try, but they may just lead to dead ends. If anyone has any information, do tell! Many people on the Internet may thank you for your contribution!
