How to get to the Cow Shrine
1. Head to the Police Station. It's marked on the map if you're clueless.
2. Enter the jail room. One will need a rat morph if wanting to attempt this.
3. Head to the second jail cell, two cells right from Bell the Officer.
4. You will see a rat hole in that jail cell. Enter and proceed.
I did not feel the need to post any pictures of the so called 'Cow Shrine' because it would ruin the need to see it.
