The Super Jump glitch can launch you around 40 feet in the air. To perform this glitch you must be using Goofy Stance, where your feet face the left side of the screen.

Try this on easy difficulty because it's much easier and when you come down you don't fall off.

You must be on COMPLETELY flat ground. Perform an FS 360 pop Shuvit, you MUST do an FS, not just a regular 360 pop shuvit.

While in the air you tap RT or LT and before you hit the ground hit the Y button. If you do it right then your character will fly high in the air.
