The Princess is a bit different from other NPCs, partially due to the fact that she can only be obtained after the player has obtained all other NPCs. She is also unique in the fact that she has no biome or neighbor preferences, as she loves living with any three NPCs living near her and is liked by all other NPCs. She is also especially prone to loneliness, as her unhappiness is maxed if she is not surrounded by either 2 or more other NPCs within 25 tiles, or 2 other NPCs that are between 25 and 120 tiles away.
