New Super Mario Bros. Wii 7-6 -- Beetle Hopping with Yoshi

This is somewhat like 5-5, but giant Parabuzzy Beetles replace the manta rays and you get Yoshi to help you. It's also an automatic sidescroller. The larger Beetles will descend when you stand on them and the smaller Beetles will ascend. All of them will squeak when you land on them and they can hurt you. Soon after you get Yoshi, who's in block hidden in the fog, there will be no ground to stand on and you have to platform using the Beetles. I got the 1st Star Coin by standing on one of the larger Buzzy Beetle and waiting for it to descend onto the Star Coin. I gotthe 2nd Star Coin by standing on the 4th smaller Beetle in a row of 6. It will ascend so you can reach the Star Coin. Afterwards, 1-ups will fall out of the sky. Catch them if you can. I got the 3rd Star Coin by riding the last larger Beetle down to the Star Coin. I went down the green pipe to reach the goal, which opens up a secret path to the Castle, that takes you in just before the boss door.
