Pampers

The fist float is the sponsor of the parade... Pampers Diapers. They are advertising their new line of cartoon diapers.

"Oh look, Y/N, what a coincidence! It looks like they're giving away free diapers to the first in the crowd to get up and dance on the float! We are sure going to need those and I bet they'll be extra generous seeing as you're already showing off their product!"

"Mom, no, absolutely not, EVERYONE would see me in... in a diaper, in ONLY a diaper."

"Oh, come on, a grown woman in a diaper with their nakey little boobies out? It's hilarious, everyone will get a kick out of it! Maybe they'll even make you their new mascot! We'd never have to pay for all the supplies you're going to be needing FROM NOW ON!"

"NO! You can't make me! This is humiliating, I am an adult, you can't do this!"

"Young lady, you get up there and dance or I will drag you up there myself, and I don't think you'll like what will happen after that! It seems that no matter how much I try to teach you a lesson in listening to your mother, you don't learn! So, you have one more chance, you get up there and shake your diapered little tushy, or disobey me again and see what happens. 3...2..."
