#taunt 1

The taunting before your next attack gives a 50% damage increase rounded up. Because of this, we can use the taunt to remove one needle hit from the BB 3 cycle. However because of some bugs, only pogo will get buffed on the Bell Beast and only if the pogo doesn't get too close to the ground. It's hard to say how high you need to be up, but the general guideline is that if you don't touch the ground with the tip of your pogo, you should be good.

The first 2 clips are of the opener.
Clip 1: the 1 silk opener. This is easier than the alternative and should be used if you can
Clip 2: no silk opener. A bit tight, but consistent. the taunt itself hits the Bell Beast (2 damage)

EDIT: Just to clarify, clip 2 does not get a taunt buff, the taunt itself does 2 damage, which, when added to the later taunt buff still makes up for 1 needle. Clip 1 does 28 damage and clip 2 does 27 damage

The third clip is the finisher you get to do if everything goes perfectly

The rest are just different ways you could try finishing if you need extra hits, they're all reletively difficult, and in some cases it might just be easier to finish with a normal 4 hits
