U just gotta duel him.

Dunno. I havnt played it ever since i beat him in a duel wich was sumint like, a year ago.

you have to give him something first dule the snake and after that i think there will be something on the ground that Toan finds and you give him goro that idem then he will join you group:)

i really wonder how you get the killer snake out after you kill those wolfs that where im
stuck

use the flut

Use the flute to draw out the snake, upon which time you need to have the Serpent Sword
equipped, as it is the only sword that can pierce through it's hard armour like skin.
