Toymaker Cap?

They're incredibely rare to get. The quests that would give that and the hammer, along with the cap are no longer do-able since they were time-limited quests. There's no saying if the quests will be back, but since they didn't come back last year it's hard to say.

They most likely won't ever come back. I just can't see how they would fit it in, it would be wired to randomly bring it back.
