The Aryankavu pooram is an annual event in the area. The vela at the Arayankavu lasts for 21 days, starting on Meenam 1. The first days are the trade fair, followed by the puppet play called Tholppavakkoothu (leather puppet play), which is a ritual art performed during the annual festivals in the Kaali temples of Palakkad district.
The theme of the play is based on the Kamba Ramayana, narrated in a diction that is a mixture of Malayalam and Tamil dialectical variations. The play covers the whole gamut of events from Lord Sree Rama’s birth to his coronation as the King of Ayodhya. The shadow play is presented in the ‘Koothumadam’, a specially constructed oblong play house on the temple premises.
On the 21st day, they have the Nayaru pooram, when the Kavalappara Moopil nayar (in old times) arrives, wearing his ceremonial outfit, holding a sword and wearing the diamond bracelets. Thus he arrives for the nilapadu nilakkal on the specially made Thara or platform. Here he meets the small chiefs of the 18 desams and provides instructions and orders
The Kavalappara family conducted the ritual coronation of a successor, much like the Zamorin, titled the Aritittuvazhcha.
