When a skeleton eats food, piles of food will spawn and if a skeleton drinks something, puddles spawn. They have special interactions like telling a skeleton joke or scaring a Sim.
It is possible to make a skeleton playable by using the cloning machine on one. Another way to make a skeleton playable is by enabling the testing cheats, shift-clicking on it, and then selecting the option to add it to the household. Either way, the added skeleton will have all skeleton features, except it will not be able to do special interactions like scaring or telling skeleton jokes. It will also have normal motives like other Sims. Trying to edit a skeleton will show it as a normal Sim, but no changes applied will be visible after exiting editing screen (except for a family screen picture, which also shows an added skeleton as a normal Sim). Skeletons added to the household in this manner are fully playable but may be removed from a family through a bug—using a relic to summon a skeleton helper can sometimes summon a playable skeleton, making it unplayable again and removing it from its family.
Added skeletons will have another glitch and will change their default colour (white, dark or blue, mosaic-like pattern) to another one from time to time. This becomes very evident when wearing earbuds.
Skeletons are able to catch fire, but cannot die from it.
Using mods,[which?] it is possible to unlock skeleton clothing in Create a Sim, which allows for a Sim to permanently possess all of the unique skeleton abilities. However, there are a number of glitches with Sims created this way:
- The skeleton's outfit cannot be changed. If the skeleton travels to a place that necessitates a different outfit, the skeleton will arrive wearing the appropriate attire, but will be unable to change out of it.
- Skeletons will have the Energized moodlet indefinitely. The moodlet will not appear if the skeleton is not currently being played.
- Skeletons will suffer from regular motive decay when on a different lot.
- Asking a skeleton to join in snorkeling may freeze the game. If the skeleton goes snorkeling by themselves, they will transform back into a regular Sim temporarily.
- Skeletons cannot pass the toxic cloud on the second level of The ██████ Lab and cannot wear a hazmat suit.
- Skeletons will constantly perform idle animations (e.g. spinning its head or playing with its ribcage) while performing other actions.
- Other Sims will panic at the skeleton whenever a lot is loaded, even if they are friends with or relatives of the skeleton.
