A toy doll assembly includes a toy doll and a separate tethered remote control unit electrically connected to the toy doll only by a two conductor cord. An electronic control unit is located within the toy doll, the electronic control unit including a signal generator for generating output signals and a controller for receiving the output signals and controlling at least two actions of the doll by detecting predetermined period variations in the received output signals, a first action being enabled upon the detection of a first predetermined period variation in the output signals and a second action being enabled upon the detection of a second predetermined period variation in the output signals. The remote control unit electrically is connected to the signal generator only by first and second electrical conductors of the cord, the remote control unit including a switch array having at least a first switch in series with a first resistance connected in parallel with a second switch in series with a second resistance, the switch array being connected between the first and second conductors so that when the first switch is closed the first resistance is connected between the first and second conductors and when the second switch is closed the second resistance is connected between the first and second conductors, the signal generator including electrical circuitry connected to at least one of the first and second conductors so that when the first switch is closed the first resistance is incorporated into the circuitry to cause the first predetermined period variation in the output signals and when the second switch is closed the second resistance is incorporated into the circuitry to cause the second predetermined period variation in the output signals.
