Big badass turtle

I was having a shisha with some friend and they started talking about the most stupid things in history but then one of them turned to me and asked me if I could make a big turte that has a rollercoaster on its back and in the rolercoaster's wagon there would be monkeys throwing purcupine, I said yeah why not sounds cool(yes I have weird friends haha). Anyways I did the turtle and since my computer can't really handle more polygons I decided to do the rest later on. So here it is.
