There's nothing I like better in the summer than heading down to the local water park. If it's raining, or if you don't have the luxury of having a water park near you then give Fanny Waterpark Slide a try.
The object of waterslide is to negotiate your way down a series of increasingly perilous flumes, collecting objects along the way. The faster you are and the more things you collect, the more points you will get.
