If you read what Perry says in a level in Hoo Wood's (the Perry Block thing) you'll hear that if you press R + START (don't use A or it won't work) you'll play a opening minigame, where you use Toad to calm other toads down and stuffs.

To get a lot of points in that minigame, and see the cut-scene on the Top Screen, grab Toad and while you're doing that go to either the left or right side of the screen then swing your stylus up and down the screen.
