Normally, a Turtum comes out to bring your flag after you have whacked your kass. Well, there is an 'Easter Egg', or hidden feature that makes a Drackonack come out with the flag instead.

You need to hit the Kass between the distances of about 800 and 830. At exactly the distance of 815, there is a small grey rock on the ground. Click on the rock with your mouse. I've found that a good way to get to this distance is to hit the Kass at a wind speed of 6 and then play normally to get the furthest score.

Now play another round, and hit the Kass again. This time a Drack will come out with the flag.
