This isn't about a mu* that's in the works, but rather a D&D one-shot campaign I am creating as an attempt to get into DMing as well as learning how to stream TTRPGs and all that. If this isn't the proper place for it, feel free to move it to a more appropriate board, mods. 
Anyhow, the premise is that it'll be taking place in two locations: A currently-unnamed bakery that appears to be haunted by pastries gone bad, and a currently-unnamed other dimension where the source of those naughty treats can be found. It'll be the party's job to take it out, of course, yadda yadda, etc.
The reason I am writing about it here is because I'd love to get some input and I can't ask any of my circle of friends in case some of them might want to play in it. I will drop ideas here as I get them and y'all can give input/advice, if you'd like.
Thanks in advance from me, who has never done anything like this before.
