I feel so awesome!
Well, this was intended for Valentine's Day, but hey, I got it done early. So here's my contribution, to let you all know that I still love Gravity Falls with a passion, and not everything I do is a cartoon crossover.
Though technically, this is a crossover. Make note of the astral spirit of Brian May possessing Mabel so she can shred some guitar, and how Tyrone can oh so skillfully keep up those piano chords. How Dipper could ever sing anything like Freddie Mercury, we'll never know. But is it enough to impress the love of his life on Valentine's Day? Well, that's up for you to decide.

This was indeed a blast to do, and was based on a visualization I always have when I listen to this Queen song. Anyway, hope you like it! I'm off to watch Boss Mabel! Stay tuned!
Oh, and music to enjoy it with.
