Finn was surfing his waves until he saw someone in danger. Quickly he surfed to them trying to rescue them from the strong ocean waves.

In a sudden flash, a glow of a large tail and orange like scales appear and are seen from the water waves. In a miracle the person who Finn was trying to save was shot up onto his board.

Once back in shore he felt the need to go back out again and investigate what he saw. He roamed in his board looking out into the horizon, wondering where that mermaid was.
