i actualy thought of something like that. Eather in the mouth or on top of the head or the tail
mabye it can shift from mouth open to mouth closed so you have a chanse of hiting it?
yes it like shoots five arrows then it´s closed for 30 seconds.
and moves fast and with slithery movements
and if you get close to the head it tries to bite you with its long teeth.
could attack with tongue and spit venom :)
