Oona has found a very special egg. Oh, how she loves her baby! She'll do anything to protect this egg until it hatches. Then she can find out what's inside, even though it might just gobble her up! But Oona's precious bundle of eggy joy may never see the light of day. It seems everyone wants Oona's egg. Her little brother Thunk, that smelly kid Bruce Brute, and a bunch of others in her West Wog world all want a piece of Oona's treasure. Oona the protector, Oona the curious, Oona the mighty will do whatever it takes to safeguard her darling. No one will get their grimy, Cro-Magnony hands on her egg. Because, more than anything, Oona wants something of her very own to care for.
