Bonehilda

Bonehilda is an NPC that was introduced in The Sims: Makin' Magic and later returned in The Sims 3: Supernatural.

The Sims: Makin' Magic
There are two versions of Bonehilda in the game. One is the janitor on the Magic Town lots A Spooktacular Spot and Vernon's Vault. The other can be bought on residential lots as a magical (and much cheaper) equivalent of Servo. This version of Bonehilda is literally a "skeleton in the closet".

If the "skeleton maid" version of Bonehilda is in her closet, clicking on the closet will give the "Knock" interaction. Selecting this will cause the selected Sim to go to the closet and knock on it, which will bring Bonehilda out to do chores. The selected Sim does not have to have magic to do this.

While the "skeleton maid" version of Bonehilda is generally equivalent to Servo, there are significant differences:

Things Bonehilda does that Servo doesn't
 * Feed a baby. Somehow, she manages to do this without waking the baby.
 * Bring in the newspaper.

Things Servo does that Bonehilda doesn't
 * Garden.
 * Attempt to entertain visitors. In fact, non-magical visitors will freak out if they see Bonehilda in action, and a hired maid will quit. A walking skeleton is one thing in Magic Town, and quite another in someone's home!
 * Serve food.

Misc. differences
 * Bonehilda seems to place a higher priority on repairing. She'll probably repair a broken dishwasher or sink before trying to use it.
 * Players can send Bonehilda back to her closet by clicking on her and selecting "Dismiss".

Bonehilda also has a few quirks. If a bar is present, she'll take a drink before heading back to her closet. Naturally, the drink will flow through her and leave a puddle on the floor. If tombstones are present, she may wave to one of them before going back to her closet. She is also a fan of the Grim Reaper, and will try to get his autograph if he appears while she's out of her closet.

The Sims 3: Supernatural
Bonehilda made a comeback in The Sims 3 in The Sims 3: Supernatural, where she plays a similar role to the one she had in Makin' Magic. She will act like a maid, keeping the lot clean and cooking meals. She will also act like a babysitter/pet-sitter, taking care of young Sims and pets, and even teaching pets some tricks. Should a fire start anywhere on the Lot, she will attempt to put it out. She stays inside the Bonehilda Living Quarters, which can be bought in the alarms section of Buy mode.

In order for Bonehilda to do chores, a Sim must "Awaken Bonehilda" at her living quarters. The Sim will wave a key, which causes her to come out. There are only two ways for Sims to interact with Bonehilda: "Dismiss Bonehilda" will allow her to go back to her living quarters, while "Chat with Bonehilda" will allow a Sim to simply chat with her.

Bonehilda has some advantages over regular maids. For one thing, she will not charge a daily fee. She can also repair broken objects, and can be awakened at any time of the day. Players can have more than one of her at a time, which can be very useful in larger households.

However, Bonehilda is an uncontrollable NPC. She cannot be a part of a household, and Sims cannot build relationships with her.

Bonehilda will drink a glass of nectar if a bottle is open and at least one glass is available. However, the nectar flows right through her, leaving a puddle in the spot where she stood when drinking. This is a throwback to her behavior in The Sims: Makin' Magic.

If The Sims 3: Ambitions is installed, she will not do the laundry.

It seems she has been based on the Grim Reaper's coding, as aging her (via cheats) will result in a 100% black skin tone female Sim (with normal flesh and bones), just like the Grim Reaper's skin tone.
