Maybe our kids are just peculiar, but at an early age they were fascinated with ants wandering around on the sidewalk, and Song was particularly careful not to step on them playing hopscotch or while using sidewalk chalk. She would inspect what they were lugging around, noted the big ones and the little ones, and liked to build enclosures around them which were inevitably unavailing as the ants simply climbed up and over. This is a good toy for a rainy day. It requires matching up the ant trails until you get to home base. It has an open character vaguely like a simple version of a Rubik's Cube.
