Wavelanding

From SmashWiki, the Super Smash Bros. wiki

Waveland is an advanced tactic similiar to wavedashing. Wavelanding is performed after a character jumps to his/her peak and descends. As the character is approaching the ground the player presses L or R, initiating an air dodge. The ground then stops the air dodge animation and begins a normal wavedash. This is especially useful for moving around platforms quickly and for getting onto the stage quickly.

Wavelanding returns in SSBB, with limited uses. It is performed by holding in a desired direction while air dodging very close to the ground. Unlike wavelanding in Melee, the length of the slide is not dependent on traction, but on the character's air speed

[edit] Wavedropping

A Wavedrop is a useful technique when trying to mantain control while you're Falling or Dashing. To Wavedrop, you must jump as high as you want, fall from a completed Aerial attack, fall from a DI, fall from a normal jump, Fast fall, or jump from a dash and hold the control stick down. Then Air dodge right before you land on the ground while holding down the control stick. You will land in a Wavedashing animation. It is Wavedashing except you don't move in any direction at all.
