The Night Pigsy can also be found in caves on the Fossil layer or can spawn on most kinds of blocks from this layer under the right circumstances in darkness. This night creature will start to burn with a blue flame when hit by sunlight (around 5:11 AM ingame-time). It will then perish without leaving any trace (nor drops/loot). Night pigsies require 18 Twig hits, 12 Wood Sword, 8 Stone Sword, 3 Obsidian Sword, 2 Iron Sword, 2 Diamond Sword, or 1 Lumite Sword hits to take out. As Pets, Night Pigsies might prefer Brown Mushrooms, Red Mushrooms or ordinary Bread as their favorite food.
