I'm pretty sure there's still at least one in Misty Mire on Tortuga. You have to go past the higher level undead near the gravestones, then it's off to the left of the Giant crab, in the corner by a shack.

There are always two or three in the jungle on Cutthroat Isle, and in El Sudoron (the jungle of Padres del Fuego). The ones on Cutthroat are probably easier to get to if you are a lower level, because you can sneak past most of the higher level undead to get to the gators.

The ones in the jungle of PDF are pretty easy to get to once you get into the jungle, but you have to go through Beckett's Quarry to get there, which can be a challenge for lower level pirates.
