Wally Mammoth lives in the Ice Age, where his huge heart warms even the coldest of days. And it has to be cold to have a sled race! Wally and his friends Otto the great auk and Wolf the (you guessed it!) gray wolf are all hot cocoa’d up and ready to compete. Otto and Wolf both really want to win, but sweet Wally is happy as long as everyone has fun.

Naturally, the competition goes downhill quickly. If the three friends careen toward the finish line in a giant snowball, how will they determine first, second, and third place? It doesn’t matter—there will be cupcakes for everyone regardless.

Wally Mammoth and the Sled Race is the first installment in a vibrant, laugh-out-loud, comic-inspired series about a group of unforgettable friends—created by friends themselves, illustrator Dalton Webb and Geisel Award–winning author Corey R. Tabor. The perfect choice for emerging readers, for developing visual literacy, and for sharing together.

Corey R. Tabor is the author and illustrator of award-winning books for children, including Mel Fell (Caldecott Honor) and Fox Has a Problem, Fox at Night, and Fox the Tiger.

Dalton Webb has worked in comics for years as a colorist, ghost artist, and font designer. This is his children’s book debut.
