Guys, i wanna help future shinobis. It is as simple as it is, be sure to camp 1 channel for 4-6 hours. then the yellow flower will pop up. make sure that you DONT CHANNEL SURF! stay on the channel you are currently on. There is also no specific place where you must stand in the mango… I have even walk around the area where the mangoes are. Also go on Keyboard mode so the “space” interaction will easily be seen.! good luck on futures shinobis out there!! ill reply if you have any questions. Its not bugged… you just need to stay focus on observing the flower popping out.
TIP: Watch an anime or a movie so you dont get bored but make sure that you can still see the mango in your screen… Pay attention to the spot where the flower will spawn cause there are other future shinobis questing as well
got it after third tries at the bottom of the left for 4hours, take note guys it has four different position now.
