Wearable Sea Pickle

Placing a Sea Pickle in the helmet slot will scale it down approximately to the size of a Villager's nose, and plant it on the player's face.

While wearing a Sea Pickle, Villagers will shake their heads much like Nitwits do and refuse to trade.

Also while wearing the Sea Pickle, actions that hurt your reputation in a Village cost twice as many popularity points.

Granted, it does contain an apparent "teasing" element, but the Villagers do stand up for themselves, just not with sticks and stones.

I'd have the Illagers and Witches be annoyed too in the name of fairness, but I think they're already considerably agitated.
