凯莉是新小孩的母亲，出现于南方公园的游戏, 南方公园：真理之杖和南方公园：完整破碎。
外观
尽管凯莉的肤色会随着新小孩设定的肤色变化，她的棕色长发，绿色衣服和黑色裤子是一直不变的。
南方公园：真理之杖
凯莉和克里斯在故事的开头搬到了南方公园，凯莉建议新来的出去交交朋友————克里斯则保证了这一建议的实施。
夫妻二人在后来的两天内基本没干什么事情，除了在新来的在森林里迷路或者在晚上乱逛的时候会把新来的抓回来“禁足”以外，只会在房子里待着。凯莉在新来的交到朋友之后会同意加好友。
打败内裤侏儒
当新来的追逐内裤侏儒的时候，新来的在通风管道中看见了父母的交谈，二人对新来的拥有的力量很担忧，凯莉甚至希望能够直接对孩子说实话，但这段本应有意义的谈话被夫妻二人的做爱终结了。于是新来的就在这这充满做爱声音的背景下继续前进，在爬出夹缝的时候，新来的跟内裤侏儒在做爱的正面背景下开战，甚至最终在床上大动作的中央打了一架。
南方公园：完整破碎
克里斯和凯莉二人均在这部游戏中扮演了更为重要的角色。在白天，凯莉会在厨房里哭着洗碗，而在晚上她的行为就夸张了一些。
酷帕国之战
从厕所出来之后，就可以看到凯莉和克里斯在对骂，双方各执一词，凯莉认为新来的拥有许多的好友和伙伴是一件好事，并直言克里斯磕的东西有问题，看见新来的走出来的时候，双方就停止争吵，凯莉去哭着洗碗了。
起源故事系列
从第一个起源故事开始，新来的就要跟浣熊侠对话，每次都要重复一遍大致的起源剧情，并且每次的结局都是新来的撞见父母做爱——浣熊侠没能理解这是普世的正常情况，坚定地把这作为新来的悲惨起源故事的重心。
返乡义务系列
每天回家都可以看见两人为了白天的学校问题争吵，凯莉每次都会证明新来的所说的信息的真实性，告诉麦奇老师和政确校长家里的实际情况，而每一次克里斯都会为此发火，因为他不想泄露家里的背景。而结果一般都是两人在孩子面前停止争吵，跑上楼继续对骂，而新来的则继续闷闷不乐地吃东西。
返乡义务
第一天，凯莉会接到麦奇老师关于问询新来的性别和性取向的电话，而回答则都是表示“早已知道”，让克里斯大发脾气，问她究竟说了什么，有没有说真话，而回答会有三种情况：
- 不，她关于儿子什么事都没说。（如果新来的自称原性男孩）
- 没错，她告诉老师女儿是个女孩了。（如果新来的自称原性女孩）
- 是，她说“已经知道孩子的性别问题了”。（如果新来的自称变性人或者“其它”性别）
不管哪种回答，克里斯都不会收住火气，而凯莉也不客气地管他叫大麻头，并生气地表示要去喝杯酒，看到新来的回家，两人便停止争吵上楼继续了。
上床之后，凯莉便会拿着酒杯去孩子的房间，告诉新来的，不管发生什么，自己都会一直爱着他，并祝愿晚安。
卧床在底
第二天的话题则变得复杂了点，因为新来的这一天不但去确认了自己的性取向和性别，还去了解了自己的种族，凯莉依然接了电话并证明了两个问题的真实性。
克里斯依然暴怒，而凯莉则依然有三种不同的回答：
- 他们的儿子感受到了巨大的困惑，他不知道家里究竟在掩藏什么，所以才大问特问自己的身份。（如果新来的自称男孩）
- 他们的女儿感觉很困惑，为什么要假扮男孩，还要掩盖自己的种族？所以才会有这么多问题的（如果新来的自称女孩）
- 孩子很困惑，所以才要去搞清楚自己的性别和种族。（如果以上两种性别都不是）
克里斯则反对，表示困惑就是掩盖的一大重点，如果孩子知道了真相，问题就会变得很大，也会很危险。而他们一发现新来的，就上楼去了。
黑夜从命
关于新来的身份的讨论在第三天变成了两人争吵“逃避现实”的方法，一边酗酒另一边吸大麻，凯莉直接去厨房喝酒了。
接着，凯莉会大醉着让新来的下去吃晚饭，克里斯则双眼通红问凯莉是不是又放了“那种药”，争吵再次爆发，两人还打了起来。
纤细白线
晚上的时候会有两种不同的情况。
- 新来的如果不是黑人，凯莉就会和克里斯一起在瓦尔莫家前面，明显晕晕的，但是依然希望自己的孩子不会偷跑出来，如果攻击他们，他们会认出新来的并且叫孩子回家，外面不安全——但他们也不能阻止孩子继续前进。
- 如果新来的是黑人，两人就会被逮捕，在警察局等着援救，被抓住的原因就是凯莉暴露了家里的种族。
During the fourth day, Chris and Kelly are violently assaulted in their house and then reveal to be held hostages by Mitch Conner, who uses them in order to blackmail The New Kid do they can do chores for him. Mitch then lies to Butthole, as he isn't going to set their parents free.
The Many Asses of Dr. Mephesto
When travelling through Mephesto's lab, the New Kid finds a room, where both Chris and Kelly are locked up. To pass through to the next room, the New Kid needs DNA from one of the parents. This involves either cutting off Chris's head or Kelly's arm, both of which will result in one of them dying. The New Kid then puts the head/arm in the scanner and can pass through.
Is later revealed that Mitch Conner took Chris and Kelly to Dr. Mephesto's laboratory, there, Kelly was attacked by Mutant Sixth Graders who broke her legs and almost ripped her left arm apart, incapacitating her as a result while Chris is placed naked on a surgical table while being trapped by a tube brace.
After surviving the many horrors of the laboratory (as Mitch Conner had deactivated the security measures), The New Kid comes across their parents. Chris informs the New Kid that they are trying to extract an organic DNA sample from one of them. Kelly informs her child that the scientists were just about to cut Chris' head off and that the only way to proceed is to finish the job, Chris hears this and insults her. After hearing what his wife says, Chris insults Kelly for not being able to keep quiet about their child powers and tells them to use their mother's arm as an organic DNA sample. The New Kid then has to kill one of them while they both beg them to spare their lives.
Explanation
In “Farts of Future Past”, the New Kid finds himself going back in time to the Origin story. He goes into the parents' bedroom, where, after seeing 2 versions of his child, Chris explains the New Kid's backstory. He explains that, when he was younger, he made a Facebook page, and managed to get 3 million followers within 3 hours. Scientists kidnapped him and Kelly and did experiments to see how their powers work. The two then fell in love and gave birth to the New Kid. They had to run away, moving from town to town, until they got to South Park. After telling the New Kids and the Coon this, they feel better and decide to live happily. After The Freedom Pals go back in time to stop the rise of Mitch Conner, The New Kid encounters their past self in the toilet, just like in the first day. The actions of Kelly are just like they were on the first day.
The New Kid, The Coon and Mitch Conner go back in time so the New Kid can stop themselves from ever seeing their parents engaging in sexual activities, they accomplish their goals and Chris and Kelly tell their child about their backstory:
Chris made a Facebook account and he already obtained a lot of followers upon joining, whereas Kelly uploaded her first Instagram picture and got five thousand followers. Their powers didn't go unnoticed, and government agents kidnapped both of them and made experiments with them in order to find out their power source. They both met in the government's laboratory and fell in love with each other, giving birth to the New Kid, who obtained a million followers upon being born. After that, the three of them escaped to prevent the New Kid from being used as a rat lab and moved from town to town in hopes of living a normal life, to accomplish this, Chris and Kelly started to put special medicine on The New Kid's dinner in hopes that it would control their powers, but the only thing it did was giving him powerful and smelly farts. After telling the truth to their child, Chris and Kelly start to feel better and they decide to lay off the marijuana and wine respectively.
Back to present day, Chris and Kelly love each other again and are glad that the three of them decided to choose South Park is a place to live, in fact, they are both so in love with each other that they decide to leave their child alone and go to their bedroom to have sex, much to the New Kid's shock, to which Professor Chaos tells him that "no matter how much [they] try to change things, [their] father will have always fucked [their] mother."
性格
凯莉似乎是两位家长中更善良的一位，真理之杖开头，她建议新来的出去找找朋友，而克里斯就直接把新来的踢出门外了。不仅如此，每天晚上她还会跟新来的说晚安。
人际关系
新来的
凯莉对新来的相当关爱，她对孩子的寂静属性毫无恶感。她还相当担心孩子会被发现，被抓走。
克里斯
在真理之杖中，两人是相当恩爱的夫妇，但在完整破碎，两人出现了吵架的现象。 When Mr. Mackey speaks to Kelly for clarification about the New Kid's sexual orientation, Chris berates her, worried people will find out the truth. This then continues until they argue all the time. Even in The Many Asses of Dr. Mephesto when The New Kid has to make a decision of who to kill, the two yell at each other from across the room and try to persuade the New Kid to kill the other one. When they tell him the truth, the two feel better and make up with each other.
冷知识
- 凯莉的原本身份设定是一位索尼工作人员，和黑色星期五三部曲的索尼微软之战对接，而克里斯则是微软的工作人员——两人的结合带来的生命是被众人所喜爱的存在。但这个设定在真理之杖完全消失了。完整破碎中则出现了她图片超级吸引力的能力。
