The 豬龍 is a 困難模式 enemy found in the 地下雪原 生物群落 when it is overlapped by 地下神聖之地, 地下腐化之地, or 地下猩紅之地. It comes in multiple colors (depending on which spreading biome it's in) and has a special ability to become transparent and nearly invisible, allowing it to fly through solid blocks. As it starts to attack, it will become visible again. When it starts moving towards the player it may also make an audible growl.
- Pigrons are Purple in the 地下腐化之地, Pink in the 地下神聖之地, and Red in the 地下猩紅之地.
- When the Pigron growls, it sounds like an oddly distorted boss noise when summoned or attacking.
- Utilizing the 狩獵藥水 makes finding and dispatching a Pigron much easier, as it glows when it would normally be nearly invisible.
- In rare cases, Underground Houses will have a functional trap consisting of a a pressure plate and a Pigron Statue, allowing them to be spawned pre-hardmode, however, it will not have any drops.
- The name is a portmanteau of the words "Pig" and "Dragon". This was confirmed by Cenx in the IRC.
- 豬龍魚公爵, and the mounts fashioned after it, Cute Fishron (summoned with the 蝦松露), and the Pigron Mount (summoned with the 帶鱗松露).
- Now has a chance to drop Bacon.
- Sprites updated.
- Now appears in greater varieties.
- 1.2.3：Now has a chance to growl when moving towards the player.
