Sarpa Raja
Sarpa-Raja ("the serpent king") is a creepy fakir who travels from village to village and exhibits himself as God-man whose parents, so he says, were a snake man and a human woman, and he also claims to be an Avatar of the Great God of Snakes.
He walks the fire, sleeps on the bed of nails and demonstrates the abilities of his serpent-like backbone which he can fold and twist in the most 'impossible' directions.
After the performance he collects all the rupees he can and moves on to the next village...
