Super Mario 3D Land: S8-5 (Airship)

We need 270 Star Coins to unlock this level. It's an Airship. Cosmic Mario's here, too. We cross some quickly spinning gears and find the first Star Coin surrounded by brick blocks. The second Star Coin is on a bridge of brick blocks. We bounce on a springy mushroom to reach a higher gear. There's more past the Airship where you think the level should end. Hop up to the higher Airship and you'll find more gears. The third Star Coin is to the left. I recommend using a Tanooki Suit here. Soon after that is the flagpole. Cosmic Mario will follow you until you reach the flagpole.
