When Circle rolls into one of Triangle's points and pops, chaos momentarily ensues until Octagon's "Stop!" brings everyone to their senses. An effortlessly rhyming text introduces us to a collection of shapes and subtly weaves their physical characteristics into traits that both lead to and solve a would-be catastrophe. Worthy of comparison to Shel Silverstein's The Missing Piece, this raucous chain of events is satisfyingly cyclical, ending just exactly where it began.
