At first I thought it was some Adventure Time inspired web series, and yes, it is, sorta. It's from Pendelwhatever, the guy from Adventure Time.
But I don't know, I think Adventure Time is funnier. Sometimes. Or maybe it's because I've been exposed to this just by 5 minutes, instead of the half hour of a TV cartoon.
I gotta say, didn't liked the ending of the episode. It's like, meh, whatever. Not enough time.
