New Super Mario Bros. Wii 8-Fort QSC

The first Star Coin is close to the star over a firebar. I timed my jump well to get it. The 2nd Star Coin is just under the 3rd, in a secret door hidden just to the left and under the midgate. It's above a large firebar, so time your jump well. The 3rd Star Coin is next to the midgate near a firebar. I got it by sliding under the ledge while timing it with the firebar. I defeated Kamek and continued.
