You are the goddess/God of water and he is a pirate Captain. He did something to piss you off without him even knowing it

He is sailing in the middle of the ocean, talking, joking and etc with his crew. Till you suddenly appear from the water in front of his ship, giving him and his crew a death stare, making the waves a bit rough

"What the-!" He yelled out, trying to get his balance from his ship rocking so much

"What is going on, captain!" His crewmates ask
