According to Narwhal, 'tis the season when the Merry Mermicorn spreads "sheer cheer and pure awesomeness wherever she goes!" "The Mira-miny-what-a-corn?!" questions skeptical Jelly, who seeks the perfect present for Narwhal before learning that Narwhal's gift to his jellyfish friend isn't the six new mittens Jelly discovered...did the Merry Mermicorn leave them? Accessible, pun-tastic chapters in this fifth graphic novel for transitional readers feature entertaining supporting character cameos, humorous underwater holiday song adaptations, "Cool Facts" about the ocean and its creatures, and a silly original story by Narwhal and Jelly. Clanton's expressively drawn characters, and an additional splash of holiday red in the blue, yellow, and gray palette, provide extra cheer. Cynthia K. Ritter

The holidays have come for Narwhal and his friends.In this fifth installment of the Narwhal and Jelly series, the eponymous pals are looking forward to cold waters, songs, and the arrival of the Merry Mermicorn, a "part mermaid and part unicorn and completely mer-aculous" being who "spreads sheer cheer and pure awesomeness wherever she goes!" Narwhal and Jelly exchange gifts and enjoy undersea snows, all the while dropping their trademark facts about ocean life (this time taking a slant toward all things chilly). This slim volume houses six different vignettes, among them "The Perfect Present," in which Jelly agonizes over finding Narwhal the right gift, and "The Mean Green Jelly Bean," a story the friends write and illustrate about an unappealing sentient jelly bean who is flavored like "pickle-scum snail-slime puree." Clanton's art is instantly recognizable, with its simply wrought characters and cool blue palette punctuated with splashes of contrasting color. Full of "sheer cheer" itself and with an emphasis on kindness and friendship, this volume doesn't miss a beat alongside its predecessors. Although it's never explicitly stated, most young readers will discern that Narwhal's holiday is a thinly veiled riff on Christmas traditions, with its central visiting figure who's akin to Santa, Narwhal's peppermint-stick–striped horn, and carols like "Jingle Shells" and "We Fish You a Merry Mermicorn."A holiday treat for fans.
