Go left and swim to the left side. Climb up there, then cross to the right and climb up to the Cannonry. The items you need (cannon starter kit and small barrel of powder) are on the mainmast to the left, above the Cannonry.
the cannoneer is in the cannonry at the top of pirate outpost island. he is on the left side of the cannonry
First, you go to the island due west of the main island. Climb up onto the dock, and past the pirate outpost sign. Go past the trading post, and climb the large skull. Go up the chain an voila!
At the Pirate Outpost, the Cannonry is at upper right. Go left to climb up first. The Cannoneer can be hird there. The flag is on the sail to the left of the Cannonry.
Swim left from the trading area, beneath the giant stone skull. One cannon is at the far left and you can climb up from there. To fire a cannon, you need the Cannon Starter Kit (fuse) from the very top of the outpost's mast.
To fire the cannons at the Pirate Outpost, you need the Cannon Starter Kit (fuses), which is at the top of the main mast. Climb up from the cannon at the lower left of the skull, jumping over the pirate, and onto the roof of the Cannonry at upper right. To the left is the mainmast and the Cannon Starter Kit. On the way back down, shove the small barrel of explosives off the mast, to the left, then down into the water. Placing it under the Golden Tooth, then shooting it, will reveal the hidden map piece.
If it is the hill with the mansion on top of it, you climb the rocks.
At the Pirate Outpost, climb up past the Cannonry to the sail, where you will find the Cannon Starter Kit (fuses). A little lower you will see a small barrel of explosives. Push it to the left, and down into the water. Place it under the giant Golden Tooth, then fire the cannon at the left side.
The small barrel of explosives is on the mast at the Pirate Outpost. Climb higher and also get the Cannon Starter Kit (fuses). Push the barrel down into the water and under the giant golden tooth. Fire the cannon at the left side to hit the barrel and blast loose the golden tooth : the map piece is under it.
The fuses are called a "cannon starter kit" and are at the top of the tall ship's mast above the Pirate Outpost. You can climb up the outpost at the left, then cross right to reach the mast from the top of the Cannonry shack. After you get the fuses, continue down the left side and pick up the small barrel of gunpowder. If you push the barrel into the water and float it beneath the Giant Gold Tooth, you have something to shoot at with the left side cannon.
Swim left to the bottom left cannon, climb up, and jump over the hostile pirate. Cross to the right and climb up and above the Cannonry. To the left, below the pirate flag, is a "cannon starter kit" (fuses) which will fire any of the 4 cannons on the outpost. There is one in particular to use, the one at lower left. On the way down the mast, push the small barrel of explosives off the yardarm to the left, and into the water below. Swim it out to just under the giant Golden Tooth. Go left and fire the cannon, trying to hit the barrel. If you do, the blast shakes loose the Golden Tooth and reveals the map piece.
The path to the top of the Pirate Outpost is a twisting one, as always on Poptropica. Follow the signs to the Corsair Cannonry at upper right.Swim to the left under the skull, or climb past the pirate at the right and cross the eye sockets to the left.Go up from the cannon at lower left, past the pirate, and to the right along the top of the skull.Jump onto the cannon, then up, or climb the chain to the Cannonry.The Cannonry is the location of the skilled Cannoneer, who you may hire once you can afford him (20,000 doubloons). Climb onto the roof, then across to the left, to the mast where the pirate flag is flying. On the mast is the Cannon Starter Kit (fuses), which fires any of the cannon at the outpost. Just below is a small barrel of explosives.(*By pushing the barrel off, into the water, and below the Golden Tooth, you can fire the cannon at left, hitting the barrel and revealing the map piece behind the tooth.)
When you first dock, run past the trading post, the skull, and jump on the island over to the right. Then go and jump to the next highest 'layer' of pirate outpost. Run over until you reach the skull. Then jump in the eye cavities until you get to the other side. Jump above the fire and on to the chain. Climb up and you are at the top.
