- Star Coin #1: A Fire Flower, Ice Flower, or Hammer Suit is required for this one, and it's in the first yellow warp pipe (which is blocked off by a Piranha Plant). Go into the pipe, and upon entering, hit the ?-Switch and throw the POW Block to claim the Star Coin.
- Star Coin #2: Go into the upwards yellow warp pipe after a series of Thwomps. Inside, there are are a bunch of Piranha Plants with the Star Coin to the right. Get it, but watch for the Piranha Plants.
- Star Coin #3: Don't hit the ?-Switch after the checkpoint, but hit the ?-Switch immediately after to reveal a secret yellow warp pipe. Upon entering the secret area, quickly run across to get to the end of the section where the Star Coin lies.
