Back-Up Moon Crystals

Then in "Luna and the Wolfies", it was revealed there was a third Moon Crystal. It was owned by Luna Girl as her back-up source of power if somebody succeeded to steal Luna Girl's Luna Magnet. It is unknown where and how Luna Girl obtained the third Moon crystal. However, the PJ Masks never got their chance to get the crystal from her at the end. Back-Up Moon Crystals are identical to Moon Crystals, except it doesn't change Luna Girl's Luna Magnet to a Luna Wand, but it is able to carry heavier objects such as the Museum.
