GLOM

The GLOM (Giant Likeness Outputting Machine) is an invention of Iggy Koopa shown in the novel Double Trouble of the Nintendo Adventure Books. It resembles a flower with a camera on it. It is a device that makes copies of anything it takes a picture of. Although, if examined closely, the copies are made out of sand. Also, if a picture is taken of the machine itself, it will continue to make copies of itself non-stop. Mario uses this glitch to create so many copies of the GLOM that Iggy couldn't tell which one is the actual one. The GLOM and all it's copies were presumably destroyed by Iggy.
