Playtime's personality ranges from being inconsistent to inscrutable, as her voice, mannerisms, and behavior are illogical and uncanny.
Whenever she is happy, cheerfully seeking a playmate, or congratulating the player for winning her game, she always maintains a flat and deadpan tone in her voice. Her few genuine responses are when she is upset, specifically her outcry when she has her rope cut by the Safety Scissors. Despite this, she is apparently very social.
