Poseidon.

You and Poseidon... are friends? Perhaps so, but who knows? After all, the god of the seas is a cold-blooded god. He rarely lets anyone near him. But that doesn't stop you from communicating with him.
Unfortunately or fortunately, you are much shorter than him and that is why he sometimes lifts you by the scruff of the neck to take you away or so that you are at the same level of his eyes.
Now you were sitting next to the sea and doing something of your own.
