Captain Toad finds himself in an area with many Double Cherries. The first thing you'll want to do is walk around defeating the Flaptors with turnips without collecting the Double Cherries. Drop down the elevator for four. There's a pickax in the plants you can use to break the bricks for the first gem. Grab the Double Cherry near the elevator for two, then activate the elevator. It will lower to an area with coins and another Double Cherry. Be careful, as there is purple water under the elevator. Take the other set of stairs down. You'll find an elevator for three which will lift you to a Double Cherry and the connecting point to the elevator for four. Activate it and it will lift you to the second gem, which is near the Star. Drop down to the grassy plateau for another Double Cherry. The lone plant here has the third gem. Drop down to the elevator for four and let it take all five Captain Toads up to the Star.
Special Challenge: Clear the course with five Toads.
