I acquired a swif decompiler. That file is wack, man. There are sprites of each of the three characters, and the background, plus something else to hold the audio behind the background. I have no idea what 'defineshapes' is for, but it seems to be the result of those sprites put to use? Not whole screenshots just a sprite in context of the resultant frame.
Oh, and the frames are a separate thing, too. There's enough to put this back together ... 163 frames, 24 pfs, and sound that is 6.74 seconds long.
