When Narwhal and Jellyfish first meet, neither can believe the other is real. “I can’t believe this! The thing I’m imagining is imagining that it is imagining me,” observes a somewhat disgruntled Jelly. Even once Jelly is convinced Narwhal is real, and agrees that Narwhal’s horn is awesome, Narwhal identifies Jelly as an imaginary friend. “We’re friends?” Jelly asks hopefully. “Sure thing!” They seal the deal by eating waffles (“Nom Nom Nom”). That opening chapter in this droll graphic novel is followed by two more stories, “Narwhal’s Pod of Awesomeness” and “Narwhal and the Best Book Ever.” Two brief interludes include “Really Fun Facts” about narwhals and jellyfish (e.g., a narwhal’s horn- like tooth can grow to up to 3 feet; a group of jellyfish is called a smack), and the “Narwhal Song” praising waffles and parties. Open-hearted Narwhal and dubious Jelly are a dynamite friendship duo. The simple, engaging line drawings are done with a limited, somewhat muted palette dominated by watery blue. (Ages 6–9)
