Shapes that Roll by Karen Nagel, illustrated by Steve Wilson

From chapters.ca:
Some shapes roll... some don't. Some shapes stack... others won't. Some shapes lie down... while others stand tall. Circles, squares, and triangles, even ovals and diamonds, are endlessly and intriguingly entertaining in Steve Wilson's world. Karen Nagel's rhythmic text is brought to life by Wilson's troupe of uniquely- shaped characters.
