Tanikai

1. On worshipping at Thanikai, the king of snakes Vasuki got his bodily wounds healed, which had been caused during the churning process in the Milky Ocean to secure the Amrita (nectar of immortality) by the devas and asuras when the Mantotra Mountain was used as the churning base and the snake king Vasuki as the rope. 
2. Sage Agasthyar Muni (of Potikai Hill) worshipped Muruga at Tanikai when he was blessed with the divine gift of the Tamil language.
