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. Wally and Wolf’s world, rendered by Webb in digital watercolor and pencil, is full of endearingly rough edges and cute details. Wally’s tiny tusks, the coils of light glowing around the sun to stretch out shadows, and the little snowman that Wolf builds while hiding are a few examples of the personality embedded in the artwork, sure to hold readers’ attention.
