tried a Demon Days cover for Gravity Falls
robbie get out, you're not part of the mystery shack crew
speaking of robbie i FORGOT HIS ZITS GODDAMN
do you like my lame album title LOL
robbie beat up dipper because dipper wanted to do a cover of disco girl
edit: think i saw a comment over on tumblr that wendy should have been in this and i MOST DEF considered it because wendy would fit in pretty awesomely with a gorillaz-esque band. but i picked mabel for the "noodle" spot. my reasoning went something like
wendy, while fun-loving, is pretty chill and laid back. around the time of phase 2 (demon days), noodle was bouncy and energetic and the big heart of the group. mabel fits those qualities a little more than wendy does. also, russel is protective of/friendly with noodle, just like soos is with mabel.
and lastly 2D and noodle are like brother/sister, and dipper and mabel are...well literally brother/sister.
...yeah i thought too much into it sorry
anyways just my personal preference!
