Pop Up Adventures: Lego Explorers

Two explorers find a map which leads them to a island in search for treasure. Where they end up looking in a forest for a ruin. There they both end up finding a golden dagger. Could this be a dagger found in some other lego sets? 

A great setting to have would be a explorer themed pop-up.It can tell a story of either pirates finding treasure, stowaways stranded from a shipwreck to explorers finding a lost artifact. This is quiet possibly the last entry it was meant to be the 1st one. Good luck to all.
