Caveboy and Cavegirl are best friends. They even share a birthday. Each wants to get the other something special for the big day, so they go shopping at Caveman Collectibles for just the right thing. But neither has money enough to buy a present for the other. So Cavegirl trades her beloved tool collection for a box to give Caveboy to store his rock collection. Likewise, Caveboy trades in his cherished rocks for a box to give to Cavegirl for her tools.
