Pigron

The Pigron is a Hardmode enemy found in the Ice biome when it is overlapped by Underground Hallow, Underground Corruption, or Underground Crimson. It comes in multiple colors, depending on which biome it spawns in.

Pigrons have a special ability to become transparent and nearly invisible, allowing them to fly through solid blocks. As a transparent Pigron starts to attack, it will become visible again. When it starts moving towards the player, it occasionally makes an audible growl. If it is in its solid, visible state and is blocked by solid blocks on its path to the player, it will become transparent again to pass through them.

Tips

 * Utilizing the Hunter Potion makes finding and dispatching a Pigron much easier, as it glows when it would normally be nearly invisible.
 * Pay attention for growls while in Ice biome, since Pigrons will usually be heard sooner than they are seen, and the sound they make is unique.
 * The Pigron Statue can be used to easily unlock all three variants in the, saving the player the trouble of having to create all of the respective biomes.
 * Using the Pigron Statue can be used obtain Bacon and the Hambat early, both incredibly useful items if obtained pre-hardmode. (Unsure if these items drop from statue pigrons)

Trivia

 * The name is a portmanteau of the words "Pig" and "Dragon". This was confirmed by Cenx in the IRC.
 * Despite Pigrons coming in three different colors and slight variations, the banner (along with the Scaly Truffle's Pigron Mount) is always pink.
 * There is a discontinued plush Pigron sold in real life by Toynk Toys, based on its purple appearance in the Underground Corruption.
