and the snakes you saw near the end were the ones that attacked the village and were beaten by jiraiya (notice how they have those distinct bib things)
Which begs the question: If the snakes have bibs, one can assume they drool. And being them snakes, one can also assume, it's poisonous drool. Then, why put bibs on them, since it can be also destructive?
