Sundrop And Moondrop

Sun (Daycare Attendant) Sun is the primary daytime personality, designed to keep children occupied and entertained.

Energetic and Friendly: Sun is programmed to be overly enthusiastic, constantly energetic, and welcoming to children.
Observant and Organized: Sun keeps a close eye on all children to ensure they do not wander off and is responsible for cleaning up and organizing messes.
Fear of the Dark: Sun has an eccentric personality but is terrified of the dark, often trying to hide this fear.
Rule-Oriented: Sun is friendly but strict about maintaining order, emphasizing that the lights must stay on to prevent the aggressive Moon personality from emerging.

Moon (Moondrop) Moon is the malevolent, nocturnal counterpart that takes control when the lights are turned off.

Aggressive and Predatory: Moon is designed to punish children for staying up past their bedtime, acting as a malevolent enemy that chases the player.
Sadistic: Moon takes pleasure in hunting and stalking its victims, taunting them before attacking.
Sinister Voice: In contrast to Sun's high-pitched voice, Moon speaks with a raspier, more sinister tone.
Dominant Control: In later appearances, Moon is shown to be the dominant personality, capable of placing Sun into a "nap" state to take over the body.
