“See this hole? I dug it. I’m a mole.” The mole appears through a softball-sized die-cut circle through the book’s jacket, cover, and first page. After that, most of the action occurs above and beneath a horizontal line that represents the above and below ground. Keep your eye on the winding red lane; that’s the mole’s tunnel beneath the earth. As she navigates, she tells about the world above and below her, a world filled mostly with curving, wiggly worms, root vegetables, and butterflies. There are a few short lines of rhyming text on every page, but Ehlert’s bold cut-paper assemblages are the real star here. A visual index at the book’s end shows labeled pictures of each of the creatures below and above ground that the mole encountered, and a final double-page spread extending through the final endpapers lays out a map to her underground home.
