- 2013.06.13 North of Mountain Cave
When you exit Mountain Cave to the north, you will find yourself in an big, expansive field. Following the Ook's tracks, you'll first need to find the Prison.
In this area, you will encounter a lot of enemies with the Wind attack attribute, so bring as many resistant Green colored Denpa Men as you can along with you and you should be fine. If possible, we also recommend bringing Denpa Men with the "Icicle" or the "On the Rocks" Antenna Powers!
