Moonspear Work hard and be nice.

Bronco wasn't sure if the shiny flecks in the wall were actually just litte tiny bits of sparkling dust or actual rocks, so when Meerkat posed the question, he padded toward one of the walls near the entrance, where the light had been best reflected. He crow-hopped sideways in surprise when the gleaming wall seemed to shift- only to realize "Ahuh, just my shadow." He said, tail waving and causing the light to almost ripple across the wall in its shadowy wake. He sniffed, and squinted, but could only see small, itty bitty baby crystals, at best, and small places in the stone where there were indeed nothing more than flecks. He wouldn't know the name for it, but he was looking at stone laden with mica, which made it look as though it was actually made from layers and layers of thin sheets of the stuff. 

"Some kind of like...shiny rock, or mini crystals in the walls," He said, but the ceiling above- that was obviously a slightly dome-shaped mess of criss-crossing crystals. He looked down, noticing some of the soft sand at his feet had a slight shimmer to it too. He pawed at it, noticing how the dust was almost like having a pawful of glitter- and padded back to Meerkat, reaching out to whipe some of the dust off down her shoulder, leaving behind a trail of slightly glittery dust that suited Meerkat's beige fur remarkably well. "Oh yeah, this is the one," He chuckled.
