One of the two lanterns were actually found today by JakThrough the combined efforts of a few people an a trade of knowledge here and there, the following were found (At least to what I know)
- a clock
- 2 different types of cannonballs
- a firecharge (is a drop)
- a stack of torches
- a crate
- a skull (is a drop)
- a cactus (is a drop)
Then the remaining ones we weren't able to figure out is-
- a lit lantern
- an unlit lantern
- an aquarium
- a green ore
Have tried so many for the aquarium and lantern I have no idea what those could be.
The other one follows the same pattern, it shouldn't be too hard to find.
The aquarium... mmmmh... Well it requires the 3 basic items you'd expect in an aquarium.
