Need help with an epic PSA

[Allav866]

Alright. I've hit a bump in the road for my first PSA. Basically, I'm making a PSA for Jigglypuff to give her a Falcon Punch attack. I'm mostly using Kirby's Captain Falcon to look at to see if I can figure out how to do this, and now I'm posting for help. :P
I made animations, and I've extracted Kirby's Effects for his FPunch, but as for the PSA itself, I'm stumped. I want to replace Jigglypuff's Side-Special, but I also have to edit her Up-Special to remove her Sing graphic, since it's being replaced with Kirby's Falcon.
I just don't know how this works, because this is my first time making a PSA. If anyone can at least point me to a tutorial that can help me with this, please do so. Any help would be appreciated.
