Seidon lives inside the underwater temple. He gives the protagonist a Wing Set and a Propeller to get to Papaya Island, along with instructions on how to use them. He is possibly the grandfather of Iwasuke, since he has a propeller and wing set in the underwater temple.
- "Hey... You managed to get here... (yawn) This is a temple under the sea. I live here. It's been a very long time. Yup, this place used to be above the sea. What? How long have I been here? Heh heh heh....well... I'll let you guess. Oh. You don't understand? Well, you're not equipped well to drive underwater. I had fun talking to, so I'll give you this. Please come and visit me again! And give you this. Let's put these on now. They look something like this. With these two parts, you'll be able to move around underwater like a fish! Here's how to use the wing set. It's a bit complex! The wing set allows you to easily change direction in the air or underwater. Also, Press the L1 button to get more flying distance, and press the L2 button to reduce it. Be sure to use the wing set underwater or you won't be able to change the direction! Do you understand?"
- (After the protagonist understood) "I see! Oh! Drive underwater towards the west from here, and you'll reach a big island. It's called Papaya Island. I wonder if it's there still?"
- His name is a reference to Poseidon, the Greek god of the sea.
