Tips
If you return him to the sea, you will receive a chest with random loot in it. You will also gain +1 Altruistic
The stronger the character that throws him back, the farther he goes and the better the rewards.
The strength ranges are 5-9, 10-14, and 15+. (may need testing?)
If you refuse to return him, you will gain +1 Egotistical. You can later consume Ishmashell to gain +10% Water Resistance.
If you have the talent five-star diner, the 10% water resistance is doubled.
