How do you get passed the pirates?

If you mean the big wall of baddies and don't have the weapon what you do is backtrack and get out of there not the level that area then at the left side you should see a hole go through it there's a star at the top right and a weapon at the bottom go down till you get to the bottom middle where there's a wrecked ship go in to the hole in the ship when your in go to the top til you see a door go through then you get your pencil (aka your weapon) wall jump up then the tut on the weapons then attack the wall of baddies

Big wall of baddies I assume well here's what you do. Get out of there go to the back of the lvl you see a hole go through the hole and in the hole at the top right is a star bottom your weapon go down til you see a ship with a hole in it go into the ship go up find the door get the weapon finish the weapon tut and stab the wall of baddies if not just stab the baddies with your weapon boss pirate knock him out with getting close and wait for the beard attack then attack his head
