A Spot of Iridescence

I slipped away from the desk to see how high I could go. The climb up the wooden bookshelf was slow because my armored boots clunked with every shelf, but then... something caught my eye between two thick books. It was a clear glass marble with a swirl of green and blue trapped inside. It shimmered just like treasure. I crept closer, feeling a little timid about disturbing the quiet dust, and gave it a gentle poke with my claw. It rolled forward with a soft rattle, reflecting the afternoon light right into my visor. I think I'll leave it hidden right here as my secret stash.
