Mount Myōboku Toads.
I found one thing very interesting.
It says , that Fukasaku and Shima are over 800 years old.
They are 8 times more older than the village of Konoha.
That means , that Mount Myōboku and Ryūchi Cave and Shikkotsu Forest are the oldest known areas of the Manga.
Also Great Toad Sage is the oldest inhabitant of the area meaning , that he's older than Fukasaku and Shima = judging by hes looks he seems to be extremely old.
I feel , that there is a connection between these hidden places and Rikudo Sennin.
I have a strong feeling , that the toads,snakes,snails where influenced by Rikudo Sennin.
Rikudo Sennin was the prodigy who discovered , created , exploited the Ninjutsu.
I think , that Rikudo Sennin had 3 followers on hes journeys to teach the ninjutsu to people , since he travelled as a monk around the world.
One of the followers was a snake.
One was a toad.
One was a snail.
When the Journey was over , the Sage gave each of the diciples a necklace with hidden powers to help them in the future.
Also the Sage gave the animals some clues and instructions to help the humans and the bjuus if needed.
Also to teach senjutsu to the chosen ones.
Any opinions on that?
Also Rikudo Sennin appeared long long long time ago.
