The Foxy Locks is an achievement prize. From which achievement do you get it?

It might be for an achievement that hasn't yet actually been released. Are there other sources that the 'Special' rarity would allow for, though, or does that rarity automatically make it an Achievement prize?

I suppose so. And it's an achievement prize because when I searched it in Shop Search it said it was one.

Hn, I never knew they added that feature beyond trades/Token Shop, and apparently haven't searched shops for a single Achievement prize since it was added xD Well, I think that was only added to Subetalodge as a new site item yesterday, so in that case, it could probably be for the achievements of the next plot steps.

EDIT: never mind
