so i put these three spoilers in the original new super mario bros. thread, but i feel like it deserves a dedicated thread, so people know exactly what they are clicking on. here are three i've found so far. it would be cool if everyone can post theirs in a similar format for those of us that like the help. to get the first canon, go to the fortress in the first world... [highlight the rest] ...somewhere to the far left of the screen there is a pipe that shoots you up to a doorway. this leads to a room with a starcoin. you will need shell mario for this. go through the opening to the right of this room, and use shell mario to break some blocks in the next room, and that's it. i don't know where this takes you seeing that i didn't have shell mario when i got to the secret room and haven't actually completed it yet. how to get to world 7 go to the ghost house in world 4. the ghost house above a canon.... go in as mini mario or have it ready in the item box. you'll need to go to the area with the p-block and the two vertical rows of red blocks. i think it is right after a doorway or doorportal. anyways. hit the pblock and go to the FAR right of the screen, and use the red blocks to get to the green pipe, but DONT go in it. jump on top of it and enable mini mario. kick off the pipe towards the right and keep wall-kicking. the rest is obvious. to get the canon in world 5, go to the ghost house... from here, go up a good amount of flights of stairs, not sure exactly how much. you will get to a point where at the far left of the screen there are three smashable blocks. jump on them, and you'll discover 3 hidden blocks arranged like a pyramid. jump on the middle one, SQUAT, and jump. it will reveal a vine. climb it FAST above the enemies that smash stuff, and let him smash an entrance to the secret door and fall below. go through, and you are in an elevator, sort of. kill the pumpkin enemies and stay in the middle of the rising platform since it wobbles. after you get to the top, exit and hit the flag pole. it takes you to world 8 hope that helps, anyone else have any?
