In the exclusive demo below, one of the many extras included in the Adventure Time: The Final Seasons DVD boxed set, the long-running Cartoon Network series gets the hip-hop treatment—in this case, a quick, rhyming outline of what later became MC Neptr and Flame P’s performance at the Battle of the Bands in Season Seven’s “The Music Hole.” Trust us: Whether you’re known to spit straight flames or not, this is one hot track.

In addition to its song demos, Adventure Time: The Final Seasons—which covers Seasons Eight, Nine and Ten—includes 53 episodes, a 44-minute special, an Adventure Time yearbook, and much more, all in a Flame Princess slipcase that continues the run of collectible die-cut slipcases released for previous seasons on DVD. The set arrives Tuesday, Sept. 4, alongside the 20+ track finale soundtrack—the day after the series finale, “Come Along with Me,” airs on Monday, Sept. 3.
