It's Punky Brewster

Mother of the Year (2x14)

Air date: Nov 22, 1986

Every little girl in the neighborhood is entering their mom in a mother-daughter contest...everyone except motherless Punky, that is. Glomer creates a mother for her, but Punky becomes brusque about it, feeling that she and Henry get along just fine. Besides, the glomley-created mother has uncontrolled glomley powers.
