Taffy's Sweet Dreams

I was on vacation somewhere, and it was our last day there. We net to the pool, which had 2 water slides. We were swimming in the pool at the bottom of the slide, occasionally climbing up and sliding down. The lifeguard was mad at us, but we left after that anyway. We went out to a park area. I saw a strange looking plant with needle like things. I put my shoe on top of it for some reason, but the needles went right through, poking into my foot. It hurt a lot, so I took off my shoe and tried to pull them out. There were only two, but it was bleeding a bit.
After that I found my brothers and we went to an area where there were two or three pools side by side. Above each one was a beach ball on a chain. When you pulled one, others would go up.
