Once you have charged after a Speed Boost, if you fall, for example, through pitfall blocks, and don't engage a sideways or Space Jump, you can start a Shinespark in mid air.

Move left or right and hit A to perform a sideways "batting" swipe to make the Miniblin fly through the air. Stun: Certain enemies, such as ChuChus, can be stunned by pounding the ground.
