Festro's Mother, is the mother of Festro. She never actually appeared in an episode, but she was referenced many times. In Stealing The Sun, Festro reveals that his mother would always take him to the beach for spring break, but unfortunately all the activities he'd try to play in he'd be disrupted or excluded and told "Disgustoid Go Home!" In Just For Kicks, Festro reveals that his mother constantly locked him in a closet, which in turn would cause him to play with his father's big shoes. From what has been implied, Fester seemed to have lived a life with neglective parents, considering his father was rarely at home and his mother constantly locked him up in a closet for being "bad". This gives a bit of insight as to why Festro acts as irresponsibly as he does.
