Pokemon XG: NeXt Gen in ROM - Other ROM Hacks Posted September 3, 2019 Could someone help me with the location of TM 21 (Zen Headbutt)? The Doku File said it is located in Kaminko's House. I searched it now for 4-5 times and couldn't find it. Is this like a Item that appears after u defeat the final boss or something? Progression wise I'm currently in gateon, ready to take the boat to citadark isle.
