Algodoo

I had nothing better to do, so I made this.
You can use it as a phunlet, but it's still a bit unstable.
If you detach it from the bg, it'll work, but may break with movement.

To flush, just pull down the valve (as a real toilet).

I didn't make any poop, but almost anything that fits in the plumbing and is not too heavy will get flushed.
