Ok there are turtle points that some people will give as karma. They will give you points if you help them and take them away if you mess with them. Some of the turtles that fly across the screen give you 50 positive karma (turtle) points. Some will take your points away. Really they're just for fun. No real rational way to explain it other than it's more exciting than post counting. Have fun here on Marlin and slay them turtles!
