Nintendo have recently released a new video showing classic glitches that can be found in Mario's first adventure, Super Mario Bros..
The video shows a compilation of various glitches the can be found in the NES classic, with the popular shell jumping trick making an appearance. A glitch that would give you lives continuously. Others include a glitch where Mario can get stuck in a plant, slide across Bowser's Castle flooring and one in which you can get a Koopa Shell to go beneath the floors surface. Players can also get Mario's sprite to animate oddly, by grabbing a mushroom to make him smaller and then collecting a Fire Flower power up, later on in the stage.
The video, which can be viewed below, is part of a celebration of all things Mario, on his 25th Anniversary.
