In addition to the cannon in peackeepers world...there is a rock that has a red bullseye on it. if you aim the cannon at it and blow fire on it to shoot the cannon ball it wil break it down. you can jump on it and get to the last dragon.

also another world (sorry I can't think of the name) ugh. I think it's the one after Magic Crafters. It's the one with the fools and you see a beam that makes some of them bigger than it'll come back around and make them smaller. Well, it's a cannon. Eventually you'll get to it, it's yellow. There are two guys at these steps blocking you from getting up them. You cannot kill them. But if you get to the cannon and fire it at them it will make them small and you'll be able to kill them and get up the steps.

Hidden Door

Go to "Magic Crafter World" and go to wizard peak. Free all dragons then go to "Artisan's World." There is a little water fall with five stones in the water. Jump on all of them in any order and a hidden door will open. Good Luck!
