Circle loves to roll -- around and around. Solid Square likes to sit still and strong. Triangle can celebrate all her good points, and always knows which direction to go. But when Scribble suddenly dashes through their ordered world -- all messy lines and energy -- Circle, Square and Triangle don't know what to think. But turns out just a zig zag here and a wavy line there are all that's needed to stir imaginations, and soon the shapes find themselves working as a team, on a course for adventure!
