On new Super Mario Brothers how do you get to the cannon on world 3?

Answer 1

1. Go to world 3
2. Go to the boo castle
3. On the part where there are ropes on the ceilng you need to hold on, fall on to the square brick then beat the level as you normally would.

Answer 2

This is easy to say, but hard to do.

Go to the part of the level in W3- the haunted house, that has a door and a ? trigger, set the trigger, and go up the staircase and go right (if you go left there is a star). Go down to the point where there is a box, with a trigger inside, and hit it. Make your way back to the staring point of this answer, and if you are quick enough, you should see an EXTRA DOOR (this might take a long time to get done, because there is of course a time limit, and a short one as well) that you go through, and the end is there.
