This is a parody, and is not endorsed by Cartoon Network, or the people who make Steven Universe. This is purely for fun.
Just wondering what other shows it might be fun to have these characters do.
I was thinking that if they played Gravity Falls, Finn would be Mabel, Jake would be Dipper, Bonnie would be Soos (Tragic backstory), and [SPOILER REMOVED] later on, although they could also switch it up and have Simon be Soos. Phoebe would be Wendy of course, and Marceline would by their Grunkle Stan.
