Sacred Oil Fountain
Some of the inhabitants of Mount Myōboku can use senjutsu, to gather natural energy. There is a sacred fountain on Mount Myōboku which produces a special oil that allows people to more easily feel the natural energy around them, but if the person is not perfectly still, becoming one with nature, he or she starts becoming a toad and eventually turns into stone. This oil can only exist in the atmosphere of the mountain, and will evaporate if taken outside. There are many statues of the frog ancestors and of people who tried to learn senjutsu, but failed and became toad statues. The statues are treated with much respect. This is where one can be thought sage mode.
