Check out the book trailer for Nugget & Fang: Friends Forever — Or Snack Time? by Tammi Sauer, illustrated by Michael Slack (Harcourt, 2013). From the promotional copy:
In the deep ocean, tiny Nugget and big, toothy Fang get along swimmingly—until Nugget’s first day of minnow school. There Nugget learns that minnows are supposed to be afraid of sharks!
To regain Nugget’s trust, Fang takes desperate (and hilarious) measures. But it’s not until his big sharp teeth save the entire school that minnows learn this shark is no foe.
Fantastically stylized artwork adds even more humor to this undersea story of unlikely friendship.
