Gravity Falls Other Theme Songs

I got bored so I do what we all do. Scroll through YouTube and watch Gravity Falls videos! Some of you might not know but originally Gravity Falls had a theme song with words to it! It was completely different so I found as many possible videos of different Gravity Falls song and put them together for your enjoyment!
And there's a special surprise for those of you who love Gravity Falls, Amphibia, The Owl House, and Star vs. the Forces of Evil at the end.
ENJOY! AND FEEL FREE TO NERD OUT TO YOUR HEARTS CONTENT!!!!
