Prehistoric animal friends Diego, Sid, Roshan, and Manny journey through the frozen landscape to return a human baby safely to his parents.

An acerbic woolly mammoth, an irreverent giant sloth, a scheming saber-toothed tiger, and an adorable human baby join forces for the coolest road trip ever in this fun-filled mammoth programme of books based on the major motion picture from Twentieth Century Fox and Blue Sky Studios. Manny, Sid, and Diego are on a mission - to return the abandoned baby human, Roshan, to his family. On this wondrous, rollicking and sometimes dangerous journey these three furry pals will learn about themselves and other another, as they form an unforgettable bond.
