Lucio works just from 9 pm to 7 am. Squeezing the belly of his/her Lucio (microswitches), a child sends an help call to the connected Lucio which detects it. The left hand of the Lucio-receiver flashes red (LED) until the child holds it (microswitch). When this thing happens, the flashing calms down and the other Lucio glows blue and starts to purr (motor). If during the night the child releases his/her Lucio’s hand, it slowly dims as the glow and purr of the other doll.
