Hi -users !I have long time playing this game, but I can't understand how to open the trunk.One of the sites I read - in the chest is the map to get to the next island.And the fact that, to open it you need the skeleton key.And so I wonder: where is it?
Dear Moderators, if I wrote in the wrong section, move the subject, please.

I don't actually play this game at survival / adventure mode. You can see it on F.A.Q. or check your controls in option.

I think when u build a log house or something ( the big house that takes allot of logs) than you would get the pick lock as i can recall.

Try digging around with a shovel.

Keep building things until you unlock tree house. When you'll finish building tree house, you'll get picklock. Go to the chest on the beach, and attempt to open it.

@ The Grim Reaper: I really don't know, maybe it works with log house, too. I can't remember, stopped playing SII long time ago.
