I marched out of my cozy tea-tin fortress and hoisted myself up to the wide, sunlit windowsill overlooking the great room! There, lying across the painted wood, rested a clear, ribbed glass marble. I nudged it forward with my wooden cutlass, bent down low, and peered right through its curved orb. Blimey, the entire living room flipped upside down, turning the carpet below into an inverted rolling sea! Finding such an optical wonder for chartin' the vast indoors can mean only one thing—time to claim me booty!
