In the morning, someone discovered a string of wet footprints on the deck, which is also the basis Captain Jack used to announce that an unidentified creature had boarded the ship.
The footprints stretched from outside the deck railing to the cabin entrance, but nobody knows where it went next.
Captain Jack has already dispatched people with instruments to conduct a thorough search on the ship.
But the little creature may have learned to 'wipe itself off', as the water stains on its body disappeared after entering the cabin.
Although Captain Jack doesn't believe in ghosts, he seems to think that the little creature and I are in cahoots, so he sent people to lie in ambush in my room.
I couldn't find the little creature outside, so I had to return to my room and wait, with Jack's men hiding in the wardrobe and bathroom.
