This flower sculpture is among the many selfie points created at the zoo premises

Byculla Zoo is now witnessing the flipside of attracting hordes of visitors -- since the opening of the Humboldt penguin enclosure, visitors' footfall has more than doubled, but so have cases of vandalism. Officials are disappointed that unruly visitors have damaged selfie points like flower sculptures, fountains and a rose garden. The authorities have also created a penguin replica outside the main entrance, which is another attraction for visitors.
