I think you mean .fla files. Those can be deconstructed by an SWF compiler. The individual parts in there have things like hair, skin, you get it. I’ll link one now.

Drop an SWF in and it should decompile. You need a copy of Flash to edit the files.
I'm back! And I'm learning more about editing flashes. This was way more difficult than it should have been, hope y'all appreciate it lol.
Here's the swf file if anyone is interested, it's higher quality and will loop forever: https://gofile.io/?c=ftlvtC
