The tree of Kookoobura

To train my warrior princesses we will travel to a secret land, The Land of the Setting Sun, whose name appears only on a single scroll from 3rd century mongolia. Anti-Japan is curved like a banana too, but the other way. Its natives walk on bo staves over tar pits and bubbling rivers of lava. They eat of the tree of Kookoobura, whose spiny fruit provides enough nutrition, and chipped teeth, that one per week sates them. They have tough mofos there. I Am The Board of Directories!!
