In "The legend of Zelda: The Wind Waker" what is the lamp found near a triangle shaped island?

Question

I was looking for treasure but I was at the wrong triangle shaped island. But I found some sort of lamp. As soon as it comes out of the water an octopus appears and starts shooting me so I drop the lamp and never discover what is was.

Answer 1

Are you sure you weren't just seeing the eyes of the octorock? They have odd yellow eyes.  

Answer 2

It might be one of those "fakes". Those are treasures that have the ring of light around them and everything but are actually duds and usually summon monsters to attack you. I found like 18 of those in a row when I was searching for the last Triforce piece my very first time playing. Those are annoying and you should just murder the monsters that appear and be on your way. Don't worry about the lamp, it most likely does nothing. Hope this helps.

Answer 3

I haven't played the game for a while but I'm pretty sure it is just one of those side items that are not really needed. kinda like sea map, they help you find your way around but you don't neeed them to complete the game.
