A depressed young man that chose to lazy about Hyrule rather than get a job. His family included his parents, Mutoh and the Old Hag of Kakariko Village, and his sister was Anju, who was especially devoted to her brother, so much so that she sent Link to deliver Cojiro? (Grog's pet Cucco?) to him in the Lost Woods to cheer him up.

Grog also appears in 'Majora's Mask'', running a Cucco Shack on Romani Ranch?.
