Ahoy, Ghost Ship Ahead! #2

While on watch in the crow’s nest, the pirate kids spot something gaining on their ship: a ghost ship! Rotten Tooth refuses to believe them, so the kids know that they have to solve this mystery themselves. They spend a night on deck waiting for the ghost ship to approach, and then they plan to board it. But is it even possible to step onto a ghost ship? And if it is, is it possible to get off of it?
