I have a theory!
Holiday in Harmony is a movie that we all have probably been looking forward to. And I'm extremely excited, but however, nobody really knows when it's officially coming out. But I have a supposed theory.
The Random House Book is being released September 7, 2021. So, it's logical to assume that the short film will be released around that time as well. Because, if you're like me, you'd buy the book before the movie came out, and then people would know what they're looking forward to.(I'm aware that the plot has already been revealed, but I mean the actual details). But this is only a fan theory that I came up with, so it isn't confirmed. And it's kind of an odd release date as well, since it's a holiday special, so don't get your hopes up too high.
And if you read all of this rubbish, I applaud you.
