I have created a mod which brings back some things from VV4. It replaces the noni with blueberries, adds soap to the lab (unfortunately not usable), those little cutting tool things leaning by the staircase, the coconut-cooking thing, the rock (that covers that hole), a wind flute, as well as the sticky plant and two "Tree of Life seedlings" at the end of the river.

VV5 Mod.zip contains:Tree of life seedlings, sticky plant, wind flute, coconut-cooker, rock
VV5 Mod2.zip contains:blackberries, cutting tools, soap

Here are some example pictures-
