The Falling Yoshi Mount is a basic trick used in Super Mario Maker that allows Mario to land on a Yoshi in midair. This trick can also be performed with a boot and is known as the Falling Boot Mount.
Dropping an enemy just before Mario lands on Yoshi will allow him to jump off it in midair. This can also be done with a Midair Shell Jump to gain even more distance.
