Charlie the Unicorn Q&A Livestream(s)
On February 24, 2016, and February 28, 2016, the FilmCow YouTube channel did animated live streams in which Charlie the Unicorn answered questions from viewers as part of a promotion for the Charlie the Unicorn: The Grand Finale Kickstarter. There may have also been other live streams in addition to these two.
February 28th Stream
The content of the February 28th stream, "Charlie the Unicorn's LIVE Oscars Spectacular!", can be found in an unlisted video, but none of the others seem to be publicly available anywhere aside from a small number of short clips that people apparently recorded via screen capture software. Given that the Oscars live stream is unlisted but technically available, it's possible that the other live streams may be also, but this is unknown.
