A penguin’s journey to reunite with his friend supplies the premise behind this understated and elegantly designed interactive introduction to antonyms. The use of large, well-integrated flaps creates a satisfying sense of motion as readers help Little Penguin travel through the green-blue water past bloblike ocean flora and a variety of fauna, flecked with grainy or marbled patterns... Sweeping blues and grays emphasize the vastness of the water keeping the friends apart, making their eventual reunion especially tender.
Little Penguin sets out on a preposition-rich swim to visit a friend on a distant iceberg. ... The visual rises and falls in Little Penguin's journey create a simple, soothing flow. A pleasing, low-key dip into the ocean of language as well as water.
The digital artwork is dark and cool, with the texture of block prints and the clean lines of papercut.
