'''Cloning''' refers to a number of glitches that allow Mario to hold [[object]]s that were not intended to be held. Typically, this happens when Mario continues to hold an [[object slot]] after the object in it has unloaded. When a new object loads into this slot, Mario will hold a reference to this new object. The name "cloning" comes from one of its main applications, which is to duplicate objects such as [[coin]]s or [[Goomba]] | '''Cloning''' refers to a number of glitches that allow Mario to hold [[object]]s that were not intended to be held.

When Mario rides on a [[Koopa Shell]] or [[Shiny Shell]], although the latter is impossible to clone, the shell object stays spawned until he runs into a [[wall]] or presses Z, which causes the shell to break. At this point, Mario sets a flag on the shell, and when the shell next updates, it unloads itself. Because a cloned shell does not update, it does not unload, allowing Mario to repeatedly ride and break a shell after cloning it. | When Mario rides on a [[Koopa Shell]] or [[Shiny Shell]], although the latter is impossible to clone, the shell object stays spawned until he runs into a [[wall]] or presses Z, which causes the shell to break.

==Premature Cloning== | |||
A '''premature clone''' is a cloned object that has some of its properties not fully loaded yet. This occurs on the first frame a nearby spawner spawns objects that can be cloned, and on that frame, the object would temporarily be placed at the origin of the course (0, 0, 0) while many of the properties are missing. | |||
A clone of such an object mimics many of the same traits. Therefore, a premature clone would, if released, be placed at the origin of the course while missing some effects. For example, a coin released prematurely will not be collected while the object is released, unlike the standard steps of cloning a coin. Using this technique, Pannenkoek2012 could complete some stages without collecting any coins where it may seem inevitable, notably in [[Mario Wings to the Sky]]. | |||
