Alex Hirsch also tweeted this. Every one of his tweets makes me like him even more. HE LIKES OVER THE GARDEN WALL! <3 Over the Garden Wall is my favorite show due to the music, but I'm so happy Gravity Falls won so it could get it's chance in the spotlight. Seriously though, this tweet is amazing. When two fandoms cross over, and not just because of cross over fan art, it makes my heart melt. Even if the creator of Gravity Falls tells my main fandom, PJO, to suck it.
