Bubblegum's Blueprint track is a track played by Princess Bubblegum, Jake, Finn, and Marceline in "What Was Missing." It failed to open the Door of the Door Lords. The track ended when Princess Bubblegum accidentally hit BMO in the face, causing it to catch on fire temporarily.

  • Marceline: Play triplet quavers in the Mixolydian mode.
  • Finn: Vibrate uvula by dampening and undampening larynx.
