Bladder

Bladder is a basic motive for Sims, pets and other life states in The Sims series. The bladder motive gradually decreases throughout the day, but decreases faster when eating or drinking. Using a toilet or other designated object causes the bladder motive to rise (i.e. relieves the need). If bladder is ignored, it will eventually become urgently low, and an accident can occur if the need is not resolved soon enough.
The bladder motive does not exist in The Sims Medieval, although using a chamberpot grants a temporary buff. The Sims 2: Castaway features a bladder motive, although Sims will not have an accident if it drops too low; instead, they will produce a roll of toilet paper and a changing booth to do their business in.
==Function==
The bladder motive decreases naturally throughout the day, and can be increased by going to the toilet. Babies and toddlers will soil their diapers when the bladder motive drops too low, although toddlers can be potty trained using a potty chair by older Sims. For males, the level of the bladder meter controls whether they sit or stand while using the toilet.
If a Sim's bladder starts to get full, they become extremely cranky; when it gets to the red, they make a wild dash for the toilet with urgency, and if they can't get there in time, the poor Sim has an embarrassing accident on the floor, which will immediately increase the bladder need, but will leave a puddle on the ground and severely affect the Sim's hygiene. In The Sims and The Sims 2, drinking a cup of coffee can make the bladder meter decrease. In The Sims 3 and The Sims 4, drinking anything decreases the bladder meter. Howling werewolves will decrease the bladder meters of any non-werewolves around them. In The Sims 2, elder Sims will take longer to use the toilet than adults do, and their bladder motive will decay more quickly. Pregnancy will also cause a Sim's bladder motive to decay more quickly.
As a rule, community lots will have public toilets of some sort. These will include urinals and toilet stalls, the former of which can only be used by males. In The Sims 2, knowledge Sims and/or neat Sims may occasionally have a minor fear of using a public toilet. "Having an accident" is a fear in The Sims 2, though it takes away more influence than aspiration.
In The Sims 2, outgoing and sloppy Sims are also able to "use" shrubs and the AquaGreen Hydroponic Garden to relieve their bladder needs. Sloppy Sims will also pee while taking a shower if their bladder need is low enough. Sims that wet themselves during a party will get the "Had an Accident at a Party" memory. In The Sims 4: Get Together, The Sims 4: Jungle Adventure, The Sims 4: Snowy Escape and The Sims 4: Werewolves, children and older Sims can use bushes to relieve their bladder motive.
In the Sims 3 smartphone edition, bladder failure has a small chance of being fatal.
In The Sims 2: Seasons , Lightning will cause All Motives to Drop, especially Bladder, be aware if your Sim is unfortunate enough to be struck, it is very likely that they will wet themselves in short order.
==Associated memories==
In The Sims 2, bladder failure can be associated with two negative memories.
Memory	Name 	Type 	Cause 	Game Dialog/Description 	Notes
 	Had an Accident 	Negative	Having a bladder failure. 	I'm so embarrassed I think I'll crawl into a hole... or at least a shower. 	If this motive is caused by the scare of a ghost or a vampire peek, then this memory will not be received. The Hygiene motive instantly depletes as a result.
 	Had an Accident at a Party	Negative	Having a bladder failure at a party.	That's the most embarrassed I've ever been! How can I ever show my face at a party again?	This memory only appears the first time this motive happens at a party. Anytime else it happens, the regular "Had an Accident" memory will be received.
==Moodlets==
===The Sims 3===
In The Sims 3, the Steel Bladder lifetime reward makes it so that Sim who purchased it no longer has to use the bathroom again. Sims will wet themselves if the "Really has to Pee" moodlet expires and gain an "Embarrassed" moodlet for wetting themselves, which gives -20 mood for 3 hours; and their hygiene drops to -100 (which is 0% of the meter, since Motives/Needs are measured in a range of -100 to 100), Sims who pee themselves in The Sims 3 will also lose a small amount of fun.
Moodlet	Name 	Mood Effect 	Time Period	From 	Game Dialog/Description 	Notes
 	Has To Pee 	No Mood Effect	2 Hours 	Low Bladder Need 	Your Sim needs to go. Like, "go." 	Switches to Really Has To Pee after duration expires. Steel Bladder Lifetime Reward prevents and eliminates this.
 	Really Has To Pee	-30 	60 Minutes 	Critically Low Bladder Need	The bladder situation really has only gone from bad to worse, find a bathroom soon!	When duration expires, Sim pees him/herself. If they pee themselves, it will cause them to have the "Embarrassed" moodlet if other Sims are in the room (unless they are a toddler or infant) and will instantly deplete the Hygiene need, causing the Sim to be "Smelly". Accidents also may cause a small drop in the Fun need. Timer will freeze when sitting in a car. Steel Bladder Lifetime Reward prevents and eliminates this.
===The Sims 4===
In The Sims 4, Sims will likewise wet themselves when the "Really Has To Pee" moodlet expires, and will then get the "Peed Self" moodlet and will be very embarrassed for 4 hours. Sims that wet themselves in a swimming pool get a special positive moodlet instead.
The Steel Bladder trait can be bought from the satisfaction reward store for 2,000 satisfaction points. It prevents the bladder need from going down normally. However, it is still possible for the meter to go down by drinking or to be fully depleted by certain traps in Temples found in The Sims 4: Jungle Adventure.
Moodlet	Name 	Effect	Emotion 	Time Period	From 	Game Dialog/Description 	Notes
 	Has To Pee 	1 	Uncomfortable 	3 Hours 	Low Bladder Need 	(Sim Name) needs to go to the bathroom! Soon! 	Switches to Really Has To Pee after duration expires.
 	Really Has To Pee	40 	Uncomfortable 	3 Hours 	Critically Low Bladder Need	If (Sim Name) doesn't get to a Toilet VERY quickly, there's going to be a puddle problem!	When timer expires, the Sim will pee self and the "Peed Self" moodlet appears.
 	Peed Self 	5 	Very Embarrassed	4 Hours 	Peeing Self 	You had an accident for holding it too long! How embarrassing! 	This moodlet will greatly increase the chance of the Sim dying from embarrassment if the Sim is a young adult or older; it does not appear if the Sim cannot get out of a swimming pool after suffering a bladder failure.
==Bladder and other life states==
*For SimBots, the equivalent of bladder is Waste Buildup. Servos and Plumbots do not have a bladder motive.
**Plumbots with the Fear of Humans trait chip have a very high chance of near-instantly wetting themselves with an oil puddle despite the lack of such a motive.
*PlantSims do not have a bladder motive.
*Mummies do not have a bladder motive.
*Vampires do not have a bladder motive.
== Trivia ==
* In The Sims 2, Ghosts, Vampires and Werewolves have ways to lower this motive, in the case of a Ghost, they will turn themselves invisible, and then appear opaque infront of their victim and scare them, causing them to experience a large drop in motives, especially bladder, they may pee themselves because of this, Vampires and Werewolves can use "Bleh!" and "Grrrr!" Respectively to have a similar effect, and Werewolves can of course Howl to do this at a large scale. 
* In The Sims Classic, Sims can have Extreme Tickle used on them, if the tickled sim's bladder motive is low enough, they may pee themselves. (Note that this requires the sim to Accept the interaction for this outcome.)
* Also In The Sims Classic, this time with the House Party Expansion Pack, Sims may tell a ghost story around a campfire, if the sim telling the story has High Charisma, then a ghost named Green Beard may appear and scare the listeners, if Listerns have a low bladder motive, they will pee themselves in fright.
* In The Sims 4, Sims who are afflicted by the "Really Has to Pee" Moodlet, will become Miserable due to the +40 points of Uncomfortable, this can be very detrimental if it happens when toilets are broken, since Miserable Sims cannot repair anything, leaving the poor sim with no choice but either, frantically find another toilet or if all else fails, to pee themselves, fortunately, Slobs can pee in the shower, which can spare them from having a accident, provided it isn't also broken.
