Wat, better known as Wet Wat, was a farmer in service to House Osgrey. He had an older brother, Wat Barleycorn.
Wat was among those that were called by Ser Eustace Osgrey to defend the Osgrey lands after a disagreement over the Chequy Water with House Webber escalated into threats of war. He was given the name "Wet Wat", derived from the time that Wat had fallen down the village well, in an effort to distinguish him from the other Wats among the forces. His older brother of the same name was given the name "Wat Barleycorn".
Wat was sent home by Ser Duncan the Tall with the others when Duncan realized that it would be futile to fight.
