Use them (or your Propeller Suit) to get a Star Coin at the very end of the bonus room. This will also lead you to the secret exit.
- Star Coin #3: After the checkpoint, there's a quicksand pit with a downwards arrow to the right of it. This quicksand pit that must be entered. This will lead you the third and final Star Coin.
Go into the exit pipe after getting the second Star Coin, then follow to the Goal Pole. It provides an access to Fossil Tunnel.
