Lug: Dawn of the Ice Age

Lug is a caveboy who would rather paint than club other caveboys. The clan even mocks him, calling him "Little Slug." Like all the other caveboys, Lug must enter the contest to become the clan's next Big Man and attempt to catch the Biggest Beast--even though he would much rather spend his days painting in his secret art cave. When Lug is banished for failing to catch a jungle llama, he thinks he is alone in the world but finds others who believe in him: his clanmate Stony and a new friend, Echo, a girl from a rival clan who can talk to animals and just may be prehistory's first vegetarian/animal rights activist. Together they face even bigger challenges--Lug discovers the Ice Age is coming and he has to bring the warring clans together to save them not only from the freeze but also from a particularly unpleasant migrating pride of saber-toothed tigers.
