I believe I've found the balancing-on-the-edge animation, and the dizzy animation (like when hit with a deku nut or when their shield breaks).  I was looking for the former 'cause I wanted to add that "O-ta" sound Marth makes to his air and spot dodges like in Melee. XD Narrowed it down to two and figured out which is which.

So, "ottotto" is the balancing-on-the-edge ani, and "furafura" is the dizzy one. There are some variations on FuraFura (like FuraSleepStart, etc.), which I guess are, obviously, the sleeping animations, though I haven't checked.

...Hopefully these are new. I don't see them on the list or anything...
