Out of all the outrageous things in that filler, this was probably the only thing that makes sense. We know for a fact that the Shinju feeds on blood, but we've also seen that the Juubi could absorb and control nature energy, the same for Kaguya. It only makes sense that this nature energy control comes from the Shinju. it would also explain why a planet only has one (else it dies out too quickly). It would also explain why Momoshiki's planet was barren, after all if it produced nature energy, why would it die?
