It is the Ice Age. The young steppe bison Wondu sets out to explore the world. Along the way, he encounters amazing giant animals that he has never seen before. He collides with the combative woolly rhinoceros, asks the giant sloth about its massive claws, competes with the giant armadillo, swiftly escapes from the dangerous saber-toothed tiger – and returns to the bison herd more curious than when he set out. The book includes plenty of factual information about the giant animals: woolly rhinoceros, giant sloth, woolly mammoth, giant armadillo, saber-toothed tiger, giant short-faced bear, and giant condor, as well as early humans.
