The map on Pirate Outpost, Skullduggery Island is in the giant skull's golden tooth. You have to get up to the top of the giant skull and shoot a cannon at the tooth and you will get the map piece. It's hard though.
It is not an address. It refers to the three hanging ferns at the residence to the far right at Bouffant Bay. To get the map piece, jump into the ferns in that order : 3rd, then 1st, then 2nd. The map piece will fall out.

Skullduggery Island.

The pirate tells you that the map piece is supposed to be at "312 Hanging Fern Place", but no such address exists. It is a code for the hanging plants at the house at the far right. Jump up into the plants from below, first hitting the 3rd (right side) plant, then the 1st, then the 2nd. The map piece will fall out.
At Golden Harbor, the map piece will appear in the curtained doorway between the 2nd and 3rd lamps. Light the 4th, 2nd, and 1st lamps in that order (considering the 5 lamps from left to right).
