They're Hee-eere

Far Cry 3 Blood Dragon Walkthrough They're Hee-eere

Objective: Leave the Cave

The exit of the cave is just ahead, but let's take a detour and go down to the right ahead instead of continuing ahead. On the lower area, go ahead till the end and jump into the water, look inside for a small chest.

 
Go back all the way, and you should see a collectible on the mini-map, it's one of [[Carlyle's Notes]]

Move out of the cave for now and you'll see your first Blood Dragons.

 
And before you get any sort of bright ideas you are better off without trying to kill these things at least till you are on level 10 or above even then you'll have a few difficulties (On HARD difficulty).
