Game Cheats!

I've been playing New Super Mario Bros. lately and learned a couple of cheats.
1.W5-boo house-how to get the cannon.First, run up all of the staircases until you get to the door on the platform above your head.Don't go in that door-it just leads to a star coin.Go up the next two staircases until the staircase is to your right.Walk to the wall to the left.Walk one step over and jump up.Take another step over and jump again.Repeat this one more time.By then you will have revealed three blocks.Jump on to the middle one and duck jump,revealing a vine.Climb up it while a puncho punches through some bricks.He will leave a hole big enough for you to climb through.As  you do , you will see a door.Go through it.The rest is pretty simple,which I will leave you to play by yourself.
