Grab the POW Block and carry it forward a little bit. Toss the POW Block to force the entire level to shake and bring down the coins hanging over head. Not only does the POW Block shake coins loose, it also destroys all of the enemies on-screen!
Stand on the girder and tilt the Wii Remote right to reach the ? Block. After grabbing the power-up in the ? Block, tilt the Wii Remote left to reach the pipe on the right side of the screen.
There's a Star in a block at Point 5. Use a Ground-Pound to bust through the bricks on the left, then hit the Block just left of the Bowser flag. Jump up through the blue floor to grab the Star, then sprint left across the remainder of the level. If you hit all the enemies along the way, you'll score at least two or three 1-Ups.
