A green worm searches for a pink worm across the pages of this interactive picture book for young children. It’s not just the pink worm that’s fun to find on each page spread, camouflaged as a mast among colorful boats, for example, or exiting page right as it crosses a bridge, or circled inside the rim of a bicycle wheel. The green worm is just as fun to spy, rising from sea grasses, or from behind tall buildings. Directional prepositions (up, down, above, below, around, inside, through, etc.) are part of the simple narrative as the pink worm describes its location. The various scenes in the brightly colored, charming gouache and paper illustrations gain context with endpapers showing the worms’ world: a small section of park that includes a pond with boats, a sandbox with buildings, bicycle riders, and more, all offered from a worm’s eye view in the story. (Ages 2-5)
