Acid? You simpleminded girl. Everyone knows that a perfect mixture of 62% bleach and 38% dairy-free milk is the best solution to fill a ball pit with. It not only burns and stings, but also has victims develop a permanent rash.
Soo like I got really bored since everyone is in like hell and then I got a really fun idea
I replaced foxy ball pit balls with acid!
Have fun swimming in it (Or not)
