Gr 1–4—With the help of his anxious jellyfish pal, goofy Narwhal expands his gastronomic horizons in this latest entry in the series. When Jelly discovers that Narwhal's diet consists solely of waffles, he encourages his friend to try a peanut butter cookie. Impressed, Narwhal eats so much peanut butter that he turns yellowish brown, much to Jelly's consternation. All the successful elements of the previous titles are on display: adorably childlike illustrations, absurdist humor, puns galore, and an emphasis on friendship. Clanton divides the book up into several digestible segments, including two pages of brief sea creature facts and a tale penned by Narwhal and Jelly starring their long-running superhero characters Super Waffle and Strawberry Sidekick. Relying on a simple text, the author/illustrator presents yet another tale brimming with whimsy and joy. VERDICT For all juvenile graphic novel collections, especially where the series is popular.—Mahnaz Dar, School Library Journal
