Fable/Collect the Hero Dolls

After you receive your first Hero Doll, either from winning at a tavern game, or receiving it by any other method, the next time you visit Bowerstone South, a little kid will run up to you and tell you about this quest.

This is an on-going quest with many parts throughout the game, so it will be broken down to each point in time where you can earn another doll.
