This September, fall in love with Fluffalo all over again in BUFFALO FLUFFALO AND PUFFALO (Random House Studio | On sale September 30, 2025 | Ages 4– 8), the delightful sequel to the nationally bestselling Buffalo Fluffalo. Author-illustrator duo Bess Kalb and Erin Kraan are back with a brand-new adventure and an adorable new character that is sure to capture the hearts of readers.

Buffalo Fluffalo first came to be when Kalb shared the silly concept with her son and was met with nonstop laughter. Determined to write a complete book that continued to make him double over, Buffalo Fluffalo took the world by storm. Since its release in 2024, Buffalo Fluffalo has landed on multiple bestseller and award lists and has sold nearly 200,000 copies across all formats. Now Fluffalo is back with a new sibling, Puffalo, who meets grumpy Fluffalo one morning with a loud wailing cry and the tiniest, shiniest eyes. At first, Fluffalo does not like Puffalo, but Crow wisely explains that he just needs time to learn and grow. Slowly, Fluffalo watches as Puffalo learns to trip, slip, gallop, and trot, and together, the two take long strolls and snuggle for naps. And even though Puffalo sometimes slows him down, Fluffalo realizes that life is much better with him by his side. 

Filled with hilarious wordplay and precious illustrations, this much-awaited companion to Buffalo Fluffalo is sure to become another read-aloud favorite. BUFFALO FLUFFALO AND PUFFALO introduces a sweet new character whose friendship with older, grumpy Fluffalo will resonate with older siblings who are hesitant about becoming a big brother or sister. Erin Kraan uses her distinct process of wood carving and inking to make each quirky and whimsical personality come to life, and Bess Kalb further enlivens the pages with her signature humor and laugh-out-loud rhymes. Follow Fluffalo on his next journey of discovering that he can’t get ennufalo of his yelly, smelly, squiggly, short—but also a tiny bit cute—little sibling.
