Twin brothers Siddharth and Rohit, 10, and Rohan Charuliya, 12, roam the streets of Sion barefoot, carrying a garba (a pot which symbolises goddess Durga), decorated with mirrors and glitter.
During the nine days of the festival, the children of road construction workers, studying in state-run Gujarati-medium schools, go to different homes, singing Navratri songs and bhajans and request people to pay them money in return.
The Rs 30 to Rs 100 accumulated in a day is used to purchase fruits and sweets to offer to goddess Durga as prasad. The savouries are offered to the deity on Dusshera and are distributed to friends and neighbours.
Like the trio, many other children of the tribal community of Vagris in Antop Hill and other parts of the city have been following this tradition during Navratri for many years.
Siddharth, Rohit and Rohan have been singing bhajans door to door during Navratri for the past two years.
"It is fun to hang out on the streets and sing to people," says Rohit.
"But some people yell at us for disturbing them," says Rohan.
The trio sets out at 8am managing to visit 15 to 20 households, making Rs 30 to Rs 50, before going home, at 12 in the afternoon, to get ready for school.
"We look forward to Navratri as we get t to go to people's houses and play dandiya" adds Rohan.
