At the main menu, hold C-Up or C-Down to raise or lower a whirlpool of water. While holding either button, press the Analog-stick to move the whirlpool across the water.
Complete all modes except practice and multiplayer and achieve an "OK" rating. Once you get an "OK" rating on all the required sections, the background color will turn green. Select any game mode other than practice mode. Then you will see a little blue guy. Select him and push a button to change him into a duck. Now when you start a game, the tedrads will be triangle, rectangular, and square-shaped pieces.
Complete all 16 practice rounds. Then, go to the options screen and there will be a new option called "Floor". This will let you chose from many different floor sets, such as the Mona Lisa and the American Flag. Also, this changes the background color of the title/options screens.
