(2) 1-3 This graphic-novel series opener is a collection of short stories about two creatures distinguished by the cabin and the tree, respectively, on the tops of their heads. In the first story, "HELLOS," Cabin Head and Tree Head run around greeting other similar beings, introducing us to a world of characters including Fountain Head, Mail Truck Head, and (sure to elicit giggles) Outhouse Head. Illustrations in soft watercolors with a typeface based on Campbell's hand lettering anchor the wacky concept. Other stories focus on Cabin Head painting portraits, Tree Head digging for treasure, and Cabin Head and Tree Head circumnavigating the Earth, walking backward to avoid having to say goodbye to each other. The humor is a mix of gentle and absurd. Humans live in the objects on the tops of the characters' heads, and children will enjoy noticing, for instance, the man sweeping the porch on Cabin Head and the child swinging in the tire swing on Tree Head. The stories themselves are classic buddy tales in the vein of Marshall's George and Martha or Ruzzier's Fox + Chick: low-stakes adventures between friends. It's a winning formula that rewards rereading.

(3) PS A young boy enthusiastically explains why he is the "best at hugging" everyone and everything. After a busy day full of hugging, he discovers it's just as nice to be hugged. Campbell's story retains its humor and accessibility in this smaller board-book trim size, thanks to plentiful white space surrounding the cartoony watercolor illustrations and a pithy, toddler-friendly text.

(2) PS This book's ebullient young narrator explains why he is the "best at hugging" everyone and everything. After a day full of hugging, the tuckered-out boy discovers it's just as nice to be hugged. The cartoony watercolor illustrations are a perfect counterpoint to the earnest text, from the round-headed boy with extra-long arms just right for hugging to the deadpan reactions of the recipients.
