There is a legend associated with the exhibition of toys that happens in South India that is known as ‘Bombe habba’ means Doll Festival in Karnataka and ‘Bomma Gollu’ Divine Presence in Kerala and Tamil Nadu and Bommala Koluvu in Telugu means Court of Toys.
Since divinity Durga required tremendous power, all different gods and goddesses transferred their power to her and that they all stood still as statues.
To respect the selflessness of those deities throughout the festival days they celebrate by keeping little dolls/statues of all Gods. Golu ends on Vijaya Dashami day
Kolu also has a significant connection with the agricultural economy of ancient India. It is said that in order to encourage dredging and de-silting of irrigation canals and riverbeds, the Kolu celebration was aimed at raising demand for clay from such activities.
