Parassinikadavu Muthappan temple in Anthoor town on the banks of the Valapattanam River (16 km from Kannur city) is a unique Hindu temple dedicated to God Shiva. and it has close tribal connection.   Here, the main deity is Sree Muthappan, whose divinity is  ritualistically  dual   - theyyam versions -Thiruvappana and Vellattam. The two are generic versions of  two types of ' Theyyam Ketti-aadal ' in the Kavu/temples of North Malabar. Sree Muthappan, is actually  a personification of two Gods – Thiruvappana (Lord Vishnu) and Vellatom (Lord Shiva).; latter in the form of a hunter.  Absent in this temple is the Satvic Brahminical form of worship, as in other Hindu temples of Kerala.

Believed to be  the caretaker of the  down trodden and  the poor. the god's life is best visually explained through a traditional dance known as Muthappan Theyyam that is performed almost daily. The ritual enactment of both the versions of Muthappan, through a visual expression of  traditional dance (Muthappan Theyyam) is the mode of worship. Unlike other Hindu temples where offering of non-vegetarian food and toddy (local brew  with low alcohol content) is a taboo,  the  traditional offerings to  God Muthappan here include Fish and toddy which are   distributed  as a sort of prasadam.
Yet another strange feature of this temple is, traditional rituals are not followed here.  Muthappan Thiruvoppana Mahothsavam is a popular  festival of the temple, celebrated for three days every year on 19, 20 and 21 of Kumbham (the days correspond to 3, 4 and 5 March).

 The tradition  has been that  the  ritualistic dance of covering minimum and maximum exposition of  Sree Muthappan, Thiruvappana and Vellattam, is daily  being displayed in the early morning and in the evening. Puthari Thiruvappana festival, conducted on 16 Vrichikam  (1 or 2 December), is the first Thiruvappana of the temple year. It  coincides with the  harvesting season of the region. The last Thiruvappana of the temple year is on 30th Kanni every year.

Legend has it the childless Parukutty Amma, wife of King of Ancharamana (Ayyankara Vazhunnor) of Eruvessi village one day while bathing in the ghat close to the river saw a basket with a baby floating in the river. She had the baby retrieved and brought him up as a gift of God.. When the boy attained the adulthood, his activities were against the long-cherished  tradition of a royal family -  eating flesh, etc When she tried to stop him, the boy gave a furious, but godly stare. realizing the stare had  the cosmic force - Shakti, that could bring about unexpected changes in the world. Rani  requested the boy to cover his eyes with a Poikannu, a type of cover for the eyes, so that his fiery stare wont frighten others. Wearing a shield on his eyes, he left the family, and passed through various villages in Malabar,  

Since he had his origin in a tribal family, at last he  reached a village called Kunnathurpadi. There, he became friendly with one Chantan. One day when the local boy was tapping toddy on the coconut palm tree,  Muthappan asked for it.  When Chantan refused, Muthappan, being a divine boy, cursed him to become a stone. Upon hearing this strange thing Chantan's wife  performed the rituals, Oottu, Tiruvappana and Amruthakalasam  to propitiate the  divine boy in the month of Dhanu. Muthappan became subdued and restored Chantan back to life. For the first time, they called the boy "Muthappan".  It is said wherever Muthappan journeyed, he was followed by a dog,  Hence, there is an idol of dog in that temple.
