Spin-Jump

The Spin-Jump is a special type of jump in Super Mario 64 performed by jumping on a Spindrift or a Fly Guy. The player will be sent up into the air while spinning, and fall down slower. This jump was originally going to be activated the same way as a Triple Jump in earlier builds of Super Mario 64, but this was later scrapped.

Reimplementation
In some personalized copies of Super Mario 64, the "Triple Spin-Jump" is reimplemented back into the game. This is either exclusive to an unlockable character, replaces the regular Triple Jump entirely, or is unlocked as the special jump given by Yoshi on the Castle Roof.
