What is this thing from Adventure Time?

For some reason I can't remember this clip that was a conglomerate of clips from a bunch of episodes, most if not all from season 5, with the clip of Finn pushing the gem up a tunnel when Marceline was going feral, the Neapolitan guy, and some other things, and I believe the adventure Time logo was completed at the end when some hole was filled by the stack of clips from all the different episodes.
