You were about 7 years old. Your parents aren't around very much because of their jobs so you usually go off to the coast by your parents' beach house.

You're carrying a plastic bucket with a collection of some shells you've found. You hear something cry out in strange high pitched screeching sounds and go to check what's making the noises. You go into a small cavern and find Sun, tangled up in an abandoned net. He's frantically clawing at the net and sand, he's bleeding slightly.
