There's a meme going around of a picture of a tabletop mini of one of those Windstream trailers on a pair of bird legs, and the DM is telling the group they'll be going to Bubba Yaga's Dancing Hut.
"Do you mean Baba Yaga?"
"No. No, I do not."
I'd been planning to create my own setting in which to run a campaign, and all I have so far is the party gets sent to speak with a dragon, who seems threatening at first, then surprises someone in the group with a big lick before asking if they're going to beg for mercy... Turns out, it's a copper dragon, just trying to have a laugh. But copper dragons also love a good caper, so he sends them to retrieve a scroll case for them. A heist commences, and when the party returns, the scroll inside is a recipe for some kind of soup. Of course, the dragon knew it was a soup recipe, which is why he sent them to get it. It's a damn good soup, apparently.
I also had an idea for an antagonist, which will require some homebrew work: a dragonborn, but not of a type found in any of the books... A cobalt dragonborn, who has similarities to the cobalt dragons of the second and third editions of D&D, such as metallic blue scales and a magnetic breath weapon. That part will definitely take the party by surprise. I was also thinking of adding in a cobra dragon (from fourth edition), and there's a really cool looking mini for one that I saw online. Picture a massive cobra with the forelegs of a dragon, and using the wings as a pair of legs. They're particularly nasty foes, but I have an idea for how to get the party to meet one.
