How do you trap the pirates on Scooby Doo high sea 4?

Answer 1

1st pirate helper: you get the rope that's dangling to the boat near the steer and tie it to the chain thing on the black floor where he always goes

2nd pirate helper: get the box next to the stairs on the bottom floor and click on the other piled up boxes, then grab the fire and when he steps on that spot under the piled boxes, and put fire on it

sorry, i don't know about the ghost pirate
