In the fortress, go to the room with the 3rd star coin. In the top right, there is a hole that you can go through. Go through WITH a shell. Then shell dash. The rest is obvious.
look up super Mario bros Cannon world 1 and level 1
You have to finish a level with the secret goal on the level closest to the cannon.
if you have unlocked a cannon you will be able to enter a level then when your at the cannon enter it like a pipe
First, you've got to look at the levels around it and find the one that is closest to the cannon. Go into the level and somewhere in it you will find a secret exit. After you have found it the cannon level will be unlocked. There are no enemies in it so no need for preparation. In the cannon level there will be the cannon a little to the left of where you start. Enter the cannon like you would a pipe and it will blast you past several worlds. To find the secret exit to the levels I suggest that you get on youtube and search for Super Mario Wii cannon level or something. Happy level skipping!
