I tried going with a hybrid of what you said, and the actual Peachette design https://www.mariowiki.com/File:NewSu...achettealt.png

Okie dokie. It's supposed to be, at least if paper mario is canon, because in Paper Mario, color splash (a game that starts alright and ends horribly), a toad is naked, no shirt, no shoes, no "pants" as they describe it, so if anything the white bulbs are pants. It's obviously just an anthro toad, but given how graphics developed, I always think it looks like a diaper.

Anywho, feel free to copy and paste this:

Toadette will find herself bout the size of princess peach if not a bit shorter, and visually I would recommend looking at your avatar that you have for Toadette, it's pretty much what I'd pick. A big pink mushroom still on her head, attached, pink hair just under it, still in pigtails, I'd say, maybe some pink hair just under the mushroom on her forehead? Maybe like a small curl or something?

Her arms and legs would be bare, she'd have brown shoes, white socks, her pink shirt and darker pink vest. Her "Pants" would turn into a thick adult diaper with pink tapes, two on each side, but that would pretty much be it. I don't know Peach's "canon height" but I'd say she's probably like 5'? So Toadette would be 4'-4'6". I think that covers it though :3.

Well, I always just liked to assume that her diaper looking bottom was just clothing of some sort. Considering other games with toads have it with other clothing on them in that area. But if you could describe how she looks now, I'd appreciate it.

Hmmm we could say her legs and feet were starting to come together. The bowel issues would be the main bit, but if anything we can say her system was changing to make ice cream, but since it didn't change her enough she'd be more easily pushing out her poop instead.

I wasn't thinking anything to extreme with her changes from the sludge.

Do we want anything to have happened to Leela physically wise? I know we said she'd have bowel issues, but anything else? Or anything specific to her bowel issues? Assuming it would tie into the fact that she was supposed to be turned into a slug that excretes ice cream.

If you don't mind, just skim over the trip to the planet they are going on a mission for. Let's say they are delivering containers or something simple, and Leela sees things as familiar, everyone else just eats the ice cream, and then she gets conked when snooping, and I'll fill in the rest.

Okay, did you want me to write all of that just immediately, or did you want it in mission style like you did before?

Alrighty then let’s say it’s a planet for ice cream instead of soda. So big winter wonderland factory, and Leela is the only skeptical one given what happened last time. But this time she goes into the back immediately to check, she’s knocked out and competent guards get her set over the vat, and no one is around to help. The guards went back to the door, but she is able to move her arms even though she’s held over the vat by robot arms.

The first option sounds pretty good.

Okay so I have two paths to take. 1 is like the slurm episode and Leela is going to be dipped into some sludge to transform her. The transformation process starts but fails and she has a bowel problem for a couple of days.

Or we do something like the bee episode and she is stung by something and feels very ill but it’s like food poisoning.
