At Night, Your on your ship sailing the seas while the other pirates are resting.

Your ship hit something, you ran to the front of the ship trying to see what it hit.

You saw a tail go down in the water and you got curious to what it was so you decide to make a trap for the next time.

The next night it comes back.

Something gets caught in the fishnet and you lift it up, it seems to be a merman.

“Oh now my day got way more interesting..” You’d say with a cocky grin.
