Quoted from Atomicboy:Is it three, I thought it was four, again, side ramp (upper I was calling it), right ramp, but in the left side shot, then hitting the ramp again gives another doesn't it? I'm pretty sure it gives a forth.
It is three. Each of the W, H, and O shots. The first O shot starts it each time you do 10, but isn't a sonic boom shot itself (and isn't worth 10Mil, x 4).
