The ruins serve as the Bat Fairies' hideout. There, they keep the stolen crystals. The crystals bring light into the dark ruins. A flickering light shines through the holes in the ruin's rock face, which are decorated with transparent crystals, illuminating the ruins. The intensity of the light in the Bat Fairies' ruins increases as more rock fragments are replaced by transparent crystal pieces in the rock face!

- The light module requires 1 x 1.5V micro battery (AAA)
