Two cavemen desire the best of everything! But will their competitive games make them happy in the end?Inch and Grub are two exquisitely hairy and competitive cavemen. Grub’s cave is bigger, and he says that makes him the best. So Inch adds a water feature to his cave. But Grub has made fire! So Inch makes a chair. And a house. And a car. Grub, meanwhile, has accumulated a castle and a train and a radio! And so the contest spirals and spirals to ever ridiculous heights … until they each have a HUGE wobbling mountain of stuff! From the humble handprint to Michelangelo's 'David' the ambition and creativity of these two characters seems limitless. But their desire to go one better than the other is in danger of toppling their friendship until, at last, they realize what is most valuable of all – each other.
