Floating

Floating is a move that can be performed by Goku and Princess Peach. This move is not an attack, but is instead more of a horizontal recovery move. When Peach or Goku use this move, they can float in midair for a limited time, and can only move left or right. If Super Saiyan Goku uses this move, he will be able to float for an unlimited time. Though only Goku and Peach have been confirmed to use this move, it has also been hinted that other characters will be able to perform this move. Those characters include Super Sonic and Super Shadow.

To do this, use your double jump and once you have double jumped, hold the jump button and you will perform this technique
