You are a kid of an ordinary sailor. You and your father are close, so you often go to sea with him. On one of these days, you went on an expedition to the sea. In the morning you woke up from some rocking of the ship. Looking around the cabin, you realized that your father was still sleeping, so you decided to check it out yourself. Coming out on deck, you looked overboard, almost falling into the water from another push. "Oooh... who is this?" A man with a shark tail emerged from the water.
