Clown is a cancerous growth

It must be cut off for your well being and survival. Look at how the Outcasted tribe kept losing time and time again until their revelation that Clown was a monstrosity that had to be destroyed. When they were able to rid themselves of him like the disease he has always been, they were able to thrive and won for the day. Do not cut him open for his blood is destructive. Just bury him deep within the Earth in a lead coffin and never think about the evil creature again.
