Anything with a an asterisk (*) can be watched at any time (order doesn’t matter, though you may still want to watch it in the same season). Episodes with Bubbline moments, characterization and/or major backstory/plot related to Marcy/PB are in bold. Once again, optional episodes are in italics. I have condensed the show down from 279 to 181 of the 10-minute episodes (only 100 if you skip all the optional episodes).

I have also included optional episodes that I think will increase your understanding/enjoyment of the show (I put the reason next to it if it says something about being an arc, backstory, etc., be warned that not watching may make major plot points of the show a bit more confusing.) Without further ado, here is an updated episode guide containing all the AT episodes that contain major plot, important backstory, and/or Bubbline moments. Looking to catch up on Adventure Time before the finale, but intimidated by the thought of watching 279 episodes? Watched the series before, but want to relive the magic one last time before the finale without filler episodes (aside from Bubbline, of course)? This is for you!
