New Super Mario Bros. Wii 7-3 QSC

I got the 2nd Star Coin by hitting an invisible block with a vine. The block is over the leftmost blue mushroom past the midgate that is part of the large nextwork of Fuzzies and blocks. I used the Propeller Suit to get it. You can also get it by using the P-Switch. I also got a 1-up at the goal.
