Teaching a pokemon Headbutt

I need it for the second region’s Marsh area, and I’m certain I once met someone offering to teach it but I can’t remember where. So where can I either find the tm or someone who teaches it?

@Dechozen101 I saw you answer a question on a similar topic so I’ll tag you, plus I saw that you were going for 100 answers on the forum

Gaea town. Iirc a blue haired woman near the benches taught it.

Epic, thanks. I’m surprised this question wasn’t already on the forum
