A Cave that is nearly impossible to see on the outside. It is behind a strong water fall. If one wishes to get to the cave, they must jump through the Waterfall. The Cave has many jewels, but be careful...Some of the jewels are traps which will throw you out of the topic. The Pokemon are a bit stronger than Mt. Bristle.
