There's an idea that's been working its way around in my head for a while. It's basically a transformation version of a slasher flick: a large, diverse group of people wind up in a mysterious location (a mansion, in this case) for some reason (they've been invited to a party) and events transpire that cause some of the group to split off from the rest (the first one to solve a puzzle gets a prize, so they go looking for clues). While so separated, they are picked off (transformed) one-by-one until finally the main group notices that there's a threat and they must work together to escape/defeat the threat (or help those who have been transformed).
Why am I mentioning this? Because I'd like some help coming up with ideas for what happens to the various party guests.
As far as plot-critical events and transformations go, I have a good number planned out. But a good slasher-style story needs non-critical targets, too - a lot of them. I need transformations and triggers to go with them. What sort of transformations am I looking for? I'm open to a wide variety, as long as the trigger is the sort of thing that would be found in an old mansion (or at a party). For example: Looking in an old bottle to see if there's a clue inside? Get sucked in and turned into a genie. Look for a clue buried in the garden? Become part of the garden. Go into the hedge maze? Every maze needs a guardian. See what's going on and decide the best course of action is to stay as still as a statue and not do anything until help arrives? End up staying still considerably longer.
Food and drink related transformations would also be good, though they would mostly play a smaller part in the story (because once things got real, who would trust any of the food?). Of course, there's no need to mention blueberry pie - that's a given.
Looking at them, all of those I've listed are disabling, and I don't want to give the idea that that's the only sort of thing I'm looking for. Non-disabling transformations (especially those that can be used as a base for further transformation) are good, too. TG? Multibreast? Animal (full or partial)? Something utterly bizarre? As long as there's a reasonable trigger, bring it on. I can't guarantee that it will be used, but I'd still like to hear it.
