Inch and Grub: a Story about Cavemen

Two cavemen invent EVERYTHING! But will they be happy? Inch and Grub are 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 made a castle and a train and a radio! And so the contest spirals and spirals ... until they each have a HUGE wobbling pile of STUFF. But what happens when the piles collapse? A funny story about being competitive and how STUFF is not what matters in life.
