On Sale: 3/3/2026

Welcome to the Nice Age! Wally is looking for his friend, Wolf. It’s time to play hide-and-seek! Come out, come out, wherever you are! A giggle-inducing, unjacketed, lower-priced hardcover picture book about friendship and competition that is perfect for emerging readers by the multiple Geisel Award–winning Corey R. Tabor and illustrator Dalton Webb. For fans of Elephant and Piggie and Narwhal and Jelly.

Wolf and Wally are playing hide-and-seek. But hiding is hard for mammoths, and seeking is even harder! Especially when Wolf has a superpower: snow white fur that camouflages perfectly with the snowy Arctic landscape.

Will Wally find Wolf? Will Wolf find Wally? And what about Otto the great auk, who discovers his own unique (and silly) hiding spot? Who knows! But there will be sweet treats all around for this sweet group of Ice Age friends.

Wally Mammoth: Hide-and-Seek is the second title in a laugh-out-loud funny, comic-inspired series about a group of unforgettable friends—created by friends themselves, illustrator Dalton Webb and the Geisel Award–winning author Corey R. Tabor. These unjacketed, lower priced, picture books make reading fun and are a perfect choice for emerging readers, for developing visual literacy, and for sharing together.
