Toadette finds herself at the base of a colorful pinball machine. Use either clear pipe cannon to launch to the top of the machine, then slide down. You'll defeat any Ant Troopers or Piranha Plants in your path. At the bottom are five small square panels. You'll need to hit each of them to lift the gate to the Star at the base. Try to hit two at a time. Near the top, you'll find spinning rings with coins and the second gem. In the center of the machine is a hole. Drop down it to find the third gem guarded by a Walleye. You'll exit near the base. When looking down at the Star from the top of the pinball machine, there is a hole on the left. Drop down it to a clear pipe cannon, then launch from it for the first gem.
Special Challenge: Do not fall into any holes.
