I've been watching Sokuno's WR for Sizzling Threat. And I was wondering how he was consistently doing Dedede's aerial so many times and how he was doing the sprint one despite staying in place. Also How hes doing that aerial so consistently with such a short hop. Tried duplicating it many times and I can't seem to do it that consistently or as fast, I eventually do the sprint hammer attack or default hammer attack. Can someone make a guide for this?

So, while the response you got is true, I will elaborate a bit. The fast spin results from dashing, hopping and attacking obviously. What is less obvious is that he is actually tapping in the opposite direction he is facing to maintain his initial position from the spin, which creates the illusion that he is staying in place. As such, if you mash right and short hop you will get the same response. The discrepancy coming from either not dashing or attacking before the hop. A tutorial can't really be made. It just comes down to mastering the button inputs frames apart. I can't get it consistently either, but I've also not practiced fast inputs extensively.

Quick question, do you use the control stick or dpad? Just curious if one is easier than the other.

I feel I should also include the fact that a quick thumb slide from A to B then B again before Dedede lands will result in a double hammer spin making him have 2 attacks per hop.

figured this shortly after posting this by myself after much practice and experimenting, but thanks anyways
