Please kind sir/madam you gotta help me, IT WOULD MEAN ALOT FOR YOU TO ANSWER... PLZ!!!!

I'm pretty sure the only way to make slow motion is to add more frames for each action your stick figure makes.
Instead of a couple frames for a punch, have like 15

Yeah, it's the same as with any animation programme. You just need to make the spacing smaller. 3 pixels per frame max should do you in pivot 3.

Gee, Thx alot now I know :D

for piv 3 to make it a slo mo, just simply make small small small movements.... easy as that
