Stir my pee

My sweet girl has recently become obsessed with the idea that pee must be stirred. Yep.
One day a couple of weeks ago she peed on the toilet and then said "I stir my pee". Then she grabbed the toilet brush and moved to put it in the toilet. I stopped her but it didn't deter her. She continues to try to stir her pee often. I don't let her and tell her the toilet brush is dirty.

I'm just hoping she doesn't try to add anything to her "pee soup".
