i can suggest feeders taking to anything of Dizzy's a bit differently to everyone else. like the concentrate hitting them entirely differently, once you get them to be able to have it, that's all they'll ever have... or get a job *at* the facility if you make it there, or if others make it there.
I wanna be able to fatten up (or be fattened up by) the woman who's described to be wearing a pink suit. The one who comes to take a lady from the care home to the Dizzy's facility.
It's my headcanon that she and the sadistic feeder that you meet if you fatten yourself into the Dizzy's facility without a feeder is actually the same person.
If nothing else, that would be a way to add that sadistic feeder personality into the rest of the game rather than having it only appear in that one niche scenario.
Sure, I'll make it possible to fatten that character. When I reach the Dizzy's & London update, I plan to include a whole host of different characters within Dizzy's & all of them will be fattenable!
I'll also make the sadistic feeder a full-fledged personality, along with a bunch of others that'll tie in with the update's themes (the war for Britain's waistlines).
