Nut jumping

Nut jumping, also known as infinite nut jumping, big seed jumping or the wet nut glitch, is an exploit that allows Mario to gain unlimited height using a large seed that has touched the bottom of any body of water. The trick has gained notoriety for being extremely difficult to repeat for many iterations, meaning only a few players have become consistent enough to gain a significant amount of height with the trick.

This glitch only works on game versions 1.1.0 and earlier.

Execution

To perform the glitch, the player must first locate one of the large seeds that are used to plant beanstalks (the exploit does not work with small seeds). The seed must then be made "wet" by placing it in a body of water and allowing it to sink to the bottom. Once Mario retrieves the seed, it will have different properties. (If the seed is placed back into water and retrieved before it sinks to the bottom, it will no longer be "wet").

If the seed respawns, it will retain its state, meaning that Mario can dunk the seed in water and wait for it to respawn rather than picking it up from the bottom of the body of water.

Once the seed has been made "wet", it gains a property that allows Mario to catch it in midair. This can be exploited to gain infinite height by repeatedly throwing the seed, diving forward and catching it again. The optimal rhythm for this trick is a triplet rhythm with roughly even spacing: throw, catch, dive, repeat. The catch can be performed either by pressing X or Y in time with the rhythm, or simply holding X or Y from the previous dive input (this is simply a matter of preference). For optimal consistency, the player should not touch the left joystick at all while performing this trick.
