Maybe... and here me out on this one because it's kinda wild...

Cows? :P

If it does end up being a YCH party, I'd love to see some taur slots for one of my 'sonas

MORE COWS!!!

Ohh a ych party sounds fun! Maybe it could be holiday or seasonal themed depending on when you hit it? Or beach themed is always fun! Or even just the usual cow or farm themed!

Something theater-related, like some folks on stage, others in the audience.

Huge YCH party was definitely on my wish list.

Theme? Oh, I don't know, was going to suggest maybe D&D with some as players and some as the adventurers, so perhaps related slots if people wanted to get 2 or partner up with someone.

Theater is pretty cool suggestion too. Some non-bovine characters would be nice too.

you could include someone with 10 boobs to represent 10k 😹💕

Maybe a giant cow YCH picture or maybe some kind of tournament to determine which character, presumably all cow characters, gets drawn up

Farm carnival

You and the Moo crew just doing what you do. oUo

I'd love to see another Mega-sized Lilly.

Feed her cakes equal to the number of followers!

For a theme suggestion: perhaps a sci-fi party to celebrate your success. Lilly as the guest of honor (and centerpiece), surrounded by, assisted and being fed by various guests (who could be having some cake, too)

I think the them should be a farmer market or a livestock show. It would be a good occasion to see make cow and other farm animals.

How fat can Lilly's hips get?
