Go into the haunted house on level five. Make sure that you have at least one power up. Go up all the steps until you see three boxes on the left side of the screen. Hit the boxes to get three coins. Climb on top of the boxes and jump up too reveal three new boxes. Jump to the left of the screen on top of the middle box and duck down and jump up. It should reveal a box with a vine if you have done it right. Climb up the vine until you can see a boxing ghost. Stay on the vine to avoid any damage from the boxing ghost. Once the ghost has gone you can climb up through the hole it has created. There should be a door there. Go through the door. You should now be on a platform. Kill the two pumpkins by stamping on top of either of them twice. Stay in the middle of the platform because it will eventually start to move. When you reach the top a pumpkin will greet you there. That's why you need a power up. That way if it touches you you won't lose the level. Go through the door which should lead you to a flag pole with a red flag on top. A path should then lead to a world eight cannon. Go inside and it should catapult you away.
