Panachikkal Bhagavathi
To the south side of the temple yard one can see a Shakteya Sanidhya called Panachikkal Bhagavathi. The legend of it origin of the idol has been described as follows:

Once, the great sage Agastya with many Maharshis was returning after worshipping Vaikkathappan on a Pradosha day. A Gandharva Kanyaka by the name Neelakundala was traveling with her family then. As she was very proud of her beauty she began laughing at the Maharshis and even the Maheswara. The sage became very angry and cursed her to become a Rakshasi . When she repented and asked for Shapa Moksha i.e. redemption of the curse the Maharshi taking pity on her said that after 86 years she will get Shapa Moksha (redemption) here in Vyaghrapadapuram.

Sthambha Vinayaka
The idol of Sthambha Vinayaka is also located in the Vaikom Shiva Temple. There is legend associated with it. Sthambha Vinayaka was in charge of the temple protection from the day Parasurama left for pilgrimage from the place. One day the cruel Rakshasi came there troubling the people and animals. The people approached Vyaghrapada Muni. He was well aware of the old story of Rakshasi and prayed to Sthambha Vinayaka. The later then ordered His servant Bhadrayush to deal with her. With the help of a Thrissul he cut the Rakshasi into three pieces. He then saw that all the three pieces transformed into the forms of three Devis. All of them then praised Vaikkathappan and Sthambha Ganapathi for granting her Moksha.

Sthamba Vinayaka then requested Vaikkathappan to grant them each a place who readily agreed. The middle piece is remaining here in the southern part of the temple yard and known as Panachikkal Bhagavati. The other Devies were sent tot Cherikkumel in the south and Koottummel in the north.
