hello! This is my first post hear, I created a holiday for sims 4 seasons with flower bunny and I thought it would be funny to add her to my household using shift click in cheats. However in CAS she is just a normal female sim. Is there any way I can get her to permanently stay the flower bunny perhaps with a mod? thank you!

Make all of her outfits bunny ones?

If you're looking to keep the thing above her name 'flower bunny' I can't help you there. But You can try making all of her outfits the same. (Except hot weather sense you dont want them to die of overheating)

Just make all her outfits as the same costume and change her name to Flower Bunny. If you want her to be cartoony sounding, raise the voice pitch all the way up. Then you would have your perfect flower bunny.
