Celebrating 10 years of Otis,  everyone's favorite tractor, created by the New York Times bestselling illustrator of  Love  by Matt de la Péna and  The Little Engine that Could  by Watty Piper! Otis is a special tractor. He loves his farm and farmer. He particularly loves the little calf in the next stall, whom he purrs to sleep with his soft motor. The two become great friends, romping in the fields, leaping bales of hay, and playing ring-around-the-rosy by Mud Pond. But when the big yellow tractor comes to the farm and replaces Otis, he is cast away behind the barn. . . until the little calf gets stuck in Mud Pond. Then there is only one tractor—and it’s not big or yellow—who saves the day. It’s little Otis! In the tradition of classics like  Mike Mulligan and His Steam Shovel  and  The Story of Ferdinand , beloved artist Loren Long has crafted an unforgettable children's classic—and character—celebrating the power of friendship and perseverance. And now a whole new age group will fall in love with Otis, the friendly little tractor, thanks to this board book edition. Let the cries of putt puff puttedy chuff begin!
