Super Gem 1: From the start, walk forward and pluck the turnip. Throw it at the Goomba. Continue forward and you'll see the first Super Gem embedded in the wall to your left. Pluck it out. Super Gem 2: Head up the ramp. At the top, rotate the camera to look behind the large block on the right. You'll see a hidden path leading to the second Super Gem. Super Gem 3: After collecting the second gem, continue along the main path. You'll encounter a Piranha Plant. Throw a turnip at it. The third Super Gem is located directly behind where the Piranha Plant was. Bonus Objective: Collect 100 coins. Explore all corners of the level, breaking blocks and defeating enemies to find enough coins. The Power Star is at the top of the central structure.
