if he gets you and coils up again, dont stop what your doing to get him off, just continue what your doing, even if that means taking care of the other snakes while hes busy trying to eat you. eventually he'll figure out that he cant, and will be more hesitant to strike since he'll know that he cant kill you or let alone eat you, and that you wont care even if he tries. theres no way around getting bit with a snake like this, you just gotta take it
