Okay, so, the first level is a very easy one to pass. Remember to hit the first item block at the top of one of the polls to get an Acorn, that will give you the ability to fly. After crossing the first pipe, remember to either use your flight powers, or just use Luigi's super jump, to get atop the highest of three moving pillars to get the first star coin. After that, try and jump high, like, off one of the tall pillars. You'll glide down safer, and avoid the squirrels. Also, you'll see the second Star coin on the side of one of the hills. Don't fly to it from the front of the hill. as it is a slanted hill, and goes up and down, and the boost may not make it. Instead, make your way to the back of the hill, and then glide towards it. Boost up after you got it, or you'll fall down and fail
