There is no cooldown on selling Clippings, as they are proof of working in the Pig Village. Clippings can be gathered from Hedges by using a Razor or Shears. Using a Razor yields 1 Clipping while using Shears yields 2.
One Shopkeep may spawn from a Town House, and will wander randomly around their house and eat any edible items left on the ground, including Pig Skin. Every so often they will drop one Manure where they are standing. If the player picks up the Manure, the nearest Pig Trader will approach and give them one Oinc, along with an accompanying quote.
Whenever there is a hostile mob nearby, or a player targets them or another Pig Trader or Royal Guard near them, they will enter a panicked state. They will begin to move around semi-randomly in a direction away from the aggressor.
They will attempt to return to their house in the evening, and if they cannot reach their house or their house is destroyed they will seek the nearest light source and stand next to it until night, at which point they will fall asleep on the ground.
