If you save and quit while you were playing in any of the special worlds, the next time you go to the home screen there will be alternate video! (Note: this can be reversed by saving and quitting in any of the first 8 worlds)
Get a Tanooki leaf.Play level 7-1.When the level starts, run towards the flag.When you come to the pit with the water, jump and hover over it.If you do this you can hit the flag and beat the level in 5 seconds, or less.
In world 1-2 there is a classic Mario throwback. After the checkpoint flag you'll see some coin blocks. If you jump on top of these you can then jump further up and away from the screen. You'll land on a small narrow ledge that you couldn't see before. You can now run past this section of the level and when you come to a gap in the higher area jump over it and keep running, you'll come to an area with a single orange pipe. Jumping in this pipe will take you to World 2.
When viewing a photograph, as with the photo album, shake the 3DS to put some objects and characters in motion. For example, shake the 3DS when viewing the photo from World 4. You will eventually see Luigi jump up from the behind the castle wall in the background.
Get the Tanooki leaf.Play stage 1-Castle.After you meet Bowser, run towards him.When you get to the gap between where you are standing and the bridge he is standing on, jump and float over the gap, using the tanooki leaf, to land where the Bowser-Button are.This makes it real easy to beat him, and gets you a much better time-score.
If Mario looks up during game play, try to go where he is looking to find hidden coins and extra life blocks.
