In the thread Escaping the "Belly of the Beast" , @ElderKoala and others discuss an adventure in which the PCs face off against candy-releated (and snack-related) adversaries, controlled by a Willy Wonka-type gone bad. It starts with the discussion of the gummy Saltwater Crocodile, and goes crazier from there. It sparked a few ideas in my head, such as Dire Gummy Bears (which @ESP77 suggests in the thread - great minds think alike!), changing the croc so that it's made of saltwater taffy rather than gummy stuffs, sugar beet les, rivals wielding licorice whips, and perhaps even a massive mobile steampunk-style mech like the one in that terrible Will Smith Wild, Wild West movie... only the whole thing is a walking candy factory that spews molten chocolate and other weaponized confections.
Admittedly, I'm going to be borrowing this idea, building on it, and running it for my players. If they're interested, I'd like to press on with more endearing, humorous, strange adventures. A dungeon crawl through a creepy amusement park. A mansion full of animated objects, including a hedge maze populated by animal topiaries and garden gnomes. Maybe even frame it all in a three-act parody of The Lord of the Rings .
What kind of weird, silly, or humorous ideas have you had for your adventures?
