Super Gem 1: As soon as you start the mine cart ride, look to your left. The first Super Gem is on a small ledge that you'll pass quickly. You need to throw a turnip at it to collect it. Aim carefully! Super Gem 2: Further along the mine cart track, you'll see a series of Piranha Plants. After passing the second Piranha Plant, look to your right. The second Super Gem is hidden behind a small rock formation. Again, a well-aimed turnip is required. Super Gem 3: Towards the end of the mine cart ride, just before you reach the disembarking point, the third Super Gem will appear directly in front of you, slightly above the track. Throw a turnip to grab it. Bonus Objective: Collect 150 coins. This requires precise turnip throwing at coin blocks and enemies during the mine cart ride. The Power Star is at the end of the mine cart ride, after you disembark.
