A Splash expo was inaugurated in the city on Wednesday. With a vast showcase of ornamental varieties of fishes, the mega aqua show on showcase at Valluvarkottam was inaugurated by director Ameer. Walking in, the mood is set with the lively beats and opening lyrics of “Boom Boom Robo-da,” coming through a life-size Rajinikanth. The Superstar has been modelled (big guns in hand) after a popular scene from Endhiran. Now, the actor may have no connection to marine world, but the appearance did make the biggest ‘splash’ of all.
