Prism Tumbling

A tiny wooden box of glass marbles sat tipped over on the low table! Click, clack, tap! I dashed forward and nudged a swirled cat's-eye sphere with my snout. It rolled right into a brass coaster, pinging against the rim! Instead of just watching, I curved my body into a tight channel. With quick jerks of my chin and mid-body, I lined up three green marbles into a neat rolling chute. When a blue marble strayed toward the table's edge, I whipped my tail around to block it, knocking it straight back into line. Instant marble alley!
