The Bath

My sister and I were on a trip into Canada, we stopped to stay at this 5 star resort. Our room was huge. My sister decided to take a bath so she started the water running. She then went to the car to get something. So I checked on the bath. The tub had rocks in the bottom. The facet was spitting up rocks along with the water. So I pulled some out and they were the size of my hand. One was painted it had green grass, a blue sky, and a flagpole with an American flag. When I started pulling out other rocks they were painted like the first.
