Princess

The Princess is an NPC vendor that will spawn once the following conditions have been met:
 * There is an empty house.
 * All other town NPCs (not including Santa Claus or town pets) are present, meaning that she can only spawn after defeating Plantera.

Living preferences
The Princess is unique in that she does not have any biome or neighbor preferences. She loves up to three NPCs that live nearby and is liked by all NPCs around her.

She also hates being lonely and her unhappiness is maxed to 150% if she is not surrounded by at least 2 other NPCs within 25 tiles, or 2 other NPCs that are between 25 and 120 tiles away.

 * The Princess has a unique death message along with the Angler, in which instead of "" the message reads "" This likely implies that she is a child, further supported by her short size. This also means she will not drop a Tombstone, even in Hardcore.
 * There is a spelling mistake in one of the Princess's quotes, where she says "the Golfer passion" instead of "the Golfer's passion".
 * The Princess has a Happiness quote for herself: "", which cannot be seen in game without third-party software, as it requires the Princess to have another Princess as a neighbor, which is impossible because two of the same NPCs cannot be alive at the same time in normal playthroughs.
 * Along with the Traveling Merchant, Zoologist, and Cyborg, she is among a small group of NPCs who sell an item post-Moon Lord. The Princess's item is a Music Box (which requires the player to defeat Moon Lord after Hardmode has been activated).
