I was talking about the Steven Universe episode Last One Out of Beach City with my coworker yesterday and she brings up Bubbleine. That reminded me I was working on an Adventure Time hack of Ben Lehman’s Hot Guys Making Out with Princess Bubblegum and Marceline as the main characters.
I need to go finish it. The four characters were Princess Bubblegum, Marceline, Finn & Jake (both controlled by a single player), and the Ice King. Everyone was written up except for the Ice King, but I have some ideas for him. Mostly about him puttering around and blaming Gunter for things that may or may not have actually happened.
