Unlock the Star Cup by winning the Mushroom Cup and the Flower Cup. Instead of getting 100 coins and doing a special move six times, go to Jr. Street (the second course) and get 100 coins. Get a blue coin and do a special move. If you are lucky, you will get three Mario heads and get 420 points. At this point, you will probably be almost through the first half. When it is the second half, repeat the strategy. You should now have at least 840 points. Quit or continue. The message 'You unlocked Glare Desert' will appear. Go there and play a little while. You should see a small green lump with spikes. Repeatedly chase and dribble on it. You should hear unusual noises if you listen closely. If you do this enough, Cactuar will pop out with an attack and run off the map. Now, simply win and quit. When you do quit, the message 'You unlocked Cactuar' will appear. His icon is a living cactus with arms, legs, eyes, mouth, and hair. He is a speed type. His special is called '1000 Needles'. Trace a backwards 'Z', begining from the top right, going to the top left, bottom right, and bottom left. Do that twice.
