Battle of the Bands

The  is a contest, hosted by Princess Bubblegum, featuring many reoccuring and main characters of the show. The event's codename is "Plan B," implying Jake and Princess Bubblegum set-up multiple plans to cheer up Finn. It is likely Princess Bubblegum is the one behind this contest, as Jake did not recall what Plan B was, even though he had an eigth note as a visual clue. The features an opening performance; it is unknown if this performance is counted in the contest. This event was interupted by Ice King's penguins, however this was not Ice King's intent, but the contest was already in chaos due to Marceline refusing to play without her special pick. The winner of the was won by a surprise performer, Music Hole. It is unclear if the audience at the stage knew about this information.

Opening act
The began with Susan Strong singing Minor Loop, a short song written by Ashley Eriksson. Susan is accompanied by Celina and Sally, performing as back-up dancers during the contest. Susan did not finish her song, as Susan interupted it, asking Jake for more bass in the moniter. Though it is possible that she already sang her final lines. It is unclear is Susan's performance was included in the contest, because Princess Bubblegum's, speech welcoming everyone for attending the contest, took place after Susan performed. It is possible that Princess Bubblegum waited for Finn to show up before she announced the contest.

MC Neptr and Flame P
The first performance after the event's announcemenr to take place was by Neptr and Flame Princess, who performed an outdated rap, taking on the apparel of 90's and earlier attire. They involved no back-up dancers, however Flame Princess did bring along Cinnamon Bun to help in selling band merchandise, which upset Ice King, because he thought they were attempting bribery.
