Man, I am good at procrastinating! I was watching Adventure Time during breakfast (and more episodes during Second Breakfast) and thought this up instead of doing things:
-Hex/Dungeoncrawl on a gonzo mountain where things use AdventureTime logic (but not lifted directly from the show, necessarily) run as a one shot whenever the fancy strikes. Mostly generated using the random generator I called, "So useful it is nearly offensive." Except everything reflavored bloopy!
-Characters are generated using MurderMaze rules, but with a focus on silly gonzo magic and teamwork rather than killing each other. Everyone starts near or with each other.
-Some kinda super quick random relationships with other PCs chart so everyone starts out having a crush, petty rivalry, good natured competition, blood brothers, or maybe you're the groups' hair stylist.
OK, now I gotta clean the stove.
