The 100G Mountain is located deep inside Area 7 in Gourmet World. It is a huge mountain, towering far above all the surrounding mountains. Acacia's soup PAIR can be captured there, as it is the place where Monkey King Bambina lives.

The mountain is made out of a rock that releases a special magnetic force which reacts to the flesh of living creatures. As you approach the peak of the mountain, gravity becomes 10 to a 100 times greater that of ground level. The mountain-area around the 100G Mountain is nicknamed the Zero Mountain Range, because of the lack of oxygen, which makes breathing impossible. The mountain is a preeminent danger zone, even within the Gourmet World. It is said that when you set foot on it, descending the mountain is impossible.
