Activa's latest advert, conceptualised and executed by Dentsu Marcom, starts with artistes singing in a train passing through picturesque hills. The lead singer is seen singing the retro classic 'Cheel cheel chillaake...arey wah wah wah', until suddenly, one of the singers spots the new Activa passing by. The protagonist bursts out singing 'Activah Vaah Vaah' instead. Co-passengers look out and on seeing the new Activa start singing along.
