unless she learned the choreography.
The others ones, it was definitely her, the other "dances" didn't require that much movement or expertise so it's likely she was doing those. It would also explain why she took a lot of time recording and rerecording.
As for the other "actors", well I do believe Sonch is definitely Sonch. Likely that Zen was also played by Sonch (based on the movements) or a choreographer, at least the bit part (the bomb bit seems to be likely a Warudo recording). And I don't have to say that Mouse and Moose didn't record their stuff and it was a Skinwalker
As for the voices, well yeah duh. There's a lot of times where they react a bit late, so it's possible that Henya and the others did voice-overs.
