Jigglypuff (SSBM)/Forward aerial
Jigglypuff pushes both feet in front of it very quickly. Has relatively low end lag allowing it to be used in succession easily. This move is a very potent edgeguarding tool and is also a very important piece of Jigglypuff's aerial game. This attack is often used as an approach tool due to its quick start-up combined with Jigglypuff being able to move away easily due to its air speed.
