Never mind kids, I know a few adults who would love to decorate their walls to look like the inside of a Super Mario Bros. game with these Nintendo Wall Decals. Made with blik Re-Stik, the decals are movable and reusable (in case you have a change of heart and decide to relocate the decals to your kid's room), and are based on the same 8-bit graphics of the original game. For $75, you get 36 decals. They also sell New Super Mario Bros. decals and Donkey Kong decals .
