天才发明家
Ever wanted to build a space rocket, invent a homework-doing machine or make your school vanish? Well, join Tracey McBean and best friend Shamus Wong, on journeys full of mystery, drama, bizarre twists and funny bits!
屈莱西是一个小小发明家，她发明的是每个孩子所向往的东西，比如“做家庭作业的机器”、“失物寻找机”等等。歇墨斯是屈莱西的好朋友，他们俩是好搭档，就好像蝙蝠侠和罗宾、袜子和衬裤一样。他们俩一直在一起搞发明创造。但是令屈莱西感到烦恼的是，家里人全都把她叫做矮子，甚至连她的小妹妹也比她长得高，她还能穿妹妹的衣服。有两个讨厌的同学也嘲笑屈莱西的矮身材。于是屈莱西为自己发明了一个延伸器……到底有用没有呢？
吉姆和杰克是兄弟俩！他们是镇上滑板极限运动的好手，但屈莱西不服气，和他们相约一比高低，看谁敢从高耸云端的山顶上往下滑。屈莱西的表哥迈凯是溜冰专家，她想靠表哥打败对手，可表哥的腿受伤绑了石膏。屈莱西在表哥的轮椅下装上滑板让他去比赛。然而比赛还没正式开始，轮椅滑板却自动从陡坡往下滑，刹车却坏了，于是屈莱西与迈凯直冲而下，两人都摔伤。屈莱西的腿也绑上了石膏无法动弹。
屈莱西有一条狗名叫山迪，它忠诚可信赖，可就是不听屈莱西的话。于是她就发明了一个训狗信号器，想让山迪服从她。但是由于屈莱西的疏忽，这个信号器不能控制狗，却能控制人。这消息被哥哥高顿偷听到了，想法把信号器弄到了手。不久，很多人都成为高顿控制的对象，高顿准备建立自己的王国，当高顿国王。屈莱西必须阻止这件事情。她突然想到山迪不受这个信号器控制，就想法让山迪抢走了信号器，高顿和其他人又恢复了正常。
屈莱西的爸爸每天早晨照镜子，发现自己掉了不少头发，担心变成秃子，妹妹梅根丢失了布娃娃，哥哥高顿的小蜘蛛不见了，妈妈又丢失了汽车钥匙，全家人总是丢东西。屈莱西发明一台失物寻找器。这台神奇的仪器居然真的能找到所有丢失的东西，还把父亲掉进下水道的头发也都找了回来，爸爸像摇滚明星般漂亮，他开心极了。可惜好景不长，没多久他又开始掉头发了。不过，妈妈在他有头发时给他拍了张照片，每当爸爸为掉头发闷闷不乐时，就拿照片给他看，他曾有过那么多头发，他曾那么英俊漂亮！
妈妈的生日快要到了，屈莱西想让母亲过一个最最快乐的生日，她苦思冥想要送一件非常特别的礼物给母亲，这位天才的发明家开动脑筋试图制造她的新发明，然而她为母亲发明的自动喷雾器，高级万能化妆机，快速擦鞋器，自动卷发帽等最终全都失败，后来她终于发明了一台自动做早饭机，可以让母亲节省时间不必动手做早饭，当她兴冲冲地请母亲来品尝这台早饭机做的早餐时，她的哥哥高顿开动机器把厨房弄得一片狼藉，屈来西很沮丧，没能让妈妈过上快乐的生日，但门铃响了，好朋友歇墨斯等送来了大蛋糕和最可口的早餐，大家一起热烈地庆祝妈妈的生日。
歇墨斯是个乐迷，他最喜欢的宇宙乐队将举行一场演出，但他没法去音乐会，因为那天他得去参加一年一度的家族团聚会，屈莱西看到歇墨斯垂头丧气闷闷不乐，便决定要帮助他。屈莱西用电脑复制了歇墨斯的照片，她想要克隆出一个歇墨斯，可以让歇墨斯既能去音乐会，同时又能去参加家庭团聚会，然而屈莱西的丰富想象力，以及她进行的试验和发明，又一次惹出了不少麻烦，但幸亏她克隆出的许多歇墨斯只存在于虚拟的网络空间里。
每年学校举行宠物日，这天大家把各自的宠物带到学校比赛，最聪明能干的，最高大的，最古怪的动物都可以获奖。歇墨斯有一只小耗子，会翻跟斗，会耍杂技动作，但不幸被麦考奈利兄弟的猫吓得逃走了。麦考奈利兄弟要歇墨斯交二十块钱，才告诉他小耗子在哪儿。屈莱西和歇墨斯替许多同学干家务活挣了二十块，却发现上了麦考奈利兄弟的当。最后小耗子回来了，歇墨斯吸取了教训，以后宠物日，他再也不带宠物而是自己装扮动物参加比赛。
每年学校组织同学野营，大家都兴高采烈地参加，可屈莱西却讨厌野营，她不喜欢野外生活，她带了充气帐篷，里面设备齐全，有彩电、微波炉、电子驱蚊器等等，还带了一台她新发明的太空联络器，想和外星人进行联系。这天，她擅自离开，跑进森林里的一个山洞，山洞里有许多萤火虫。屈莱西与萤火虫成了朋友。老师焦急地带同学们找到她后，却没人相信她能和萤火虫谈话，屈莱西十分失望，不过，让她高兴的是，野营终于结束了，大家收拾行装回家，她又可以继续自己的发明创造。
学校要举行一次知识竞赛，老师选中歇墨斯代表班级参加，歇墨斯非常紧张。屈莱西便发明了一台知识输入器，她想把计算机上的全部知识和信息输入歇墨斯的大脑，但没想到强电流使歇墨斯的头膨胀得硕大无比，并且让歇墨斯发疯了，他出现了幻觉，认为自己是外星人，他变得粗暴蛮横，要统治全地球。屈莱西想尽办法，总算让歇墨斯恢复了正常，然而天才发明家却并不吸取教训，她仍然发挥奇思异想不断地进行发明。
一年一度的暑假终于来临了。可是假期一开始，天就下起雨来。两个星期后雨还在下，好好的计划都被雨破坏了。所有的孩子都只能呆在室内玩一些无聊的游戏。屈莱西造了一幢大房子，周围用帘子遮了起来，这样雨就不会下到房子里了。房子里开了许多电灯，简直就像太阳一样，于是他们又拥有了自己的夏天。而其他孩子，如麦考奈利兄弟只能在雨里玩耍。可屈莱西在大房子里没玩多久，暑假就差不多快结束了。屈莱西想出个办法，能让自己不停地玩，她让所有的钟都停在了四点，这样一来，假期就可以一直继续下去了。但是除了屈莱西，房子里的其他人都累得够呛。虽然假期并没有能永远继续下去，不过至少延长了三天，但是这三天的作业却没有完成，屈莱西和歇墨斯只得用整个周末把作业补完。
学校里教戏剧课的卡莫迪太太写了个剧本让同学们参加演出，如果不能按时上演这出戏，卡莫迪太太就不能再任教了。为了帮助卡莫迪太太不丢饭碗，屈莱西鼓励全体同学参加，还担任舞台监督，并为这出戏设计了专门的装换布景机、喷雾器等等，演出当天，虽然闹了许多笑话，但观众们十分开心，因为演出有意想不到的好效果。一场闹剧却受到了观众们的热烈欢迎。
屈莱西新研制的飞机掉入湖底，麦考奈利兄弟骗她湖里有妖怪，想阻止她去打捞飞机残骸，屈莱西不相信，她研制了潜水器潜入湖中拍到了一些照片。这些照片被麦考奈利兄弟偷走，欺骗新闻媒体他们发现了世前恐龙，这个消息顿时引起了轰动，记者纷纷前来采访麦考奈利兄弟。屈来西及时揭穿了他们的谎言，她制造了一条叫“妖怪号”的船，当记者在公园湖上采访麦考奈利兄弟时，她驾驶着“妖怪号”吓唬了他们一通，同时也让人们知道世界上根本不存在妖怪。
The homework hound is on attack and whatever Tracey and everyone else do, they always get attacked by the hound. Then, the next day, their homework would be piled up in front of the school gate. She had to find out about that hound. While she was completing her invention with Shamus, Megan, her little pesky sister, wants to know how that thing works. Tracey and Shamus made up something that would scare her away. But instead it made her curious. So, Megan wants something to be invisible, Tracey is going to make her invisible. But she couldn't really make her invisible. While Megan was in the stage of being invisible, she also found out that the homework hound, was really Claw, Jim and Jake's dog.
When Shamus goes for something, he goes for it one hundred percent. This year it was frogs and he knows frogs more than any other kid. Shamus is just to drop out another frogs in a little pond when the mischevious brothers showed up with a racing car. This really annoyed Tracey and Shamus. The two borthers kept messing up the place, so, the two of them had to beat them in their own game. The only problem is that they don't know how to drive. So, they ask Uncle Arthur for help.
Tracey and Shamus plan out a costume for the fancy dress party at their school. While they're planning for the party, they also make the alien spaceship as one of their props and somehow it malfunctions.
Shamus' bike is a collector's item, but not all the people appretiate it. Especially, the McConaly brothers. Shamus secretly wants a new bike, and Megan, give the duo a very riduculous advice but a great idea. So they invent the Rainbow Machine. The Rainbow Machine is a success for earning money and also a target object for the McConalys to steal.
Tracey is going to join this year's kite festival but the only problem is that she just had to invent the perfect kite. Too bad she's stuck with chores and homework. All she needs is an assistant that would do the mindless work while she gets on her kite. So much for having an assistant. Robo Tracey gets all the attention from the real Tracey's family. So, Tracey decided to make her own robot family. The kite festival is just about to arrive and the two Traceys just made up the same kite. The two of them were flew up in the air and the McBeans and the robots just had to work together to get them back on the ground. But in the end, it was just one McBean family is enough.
When Mrs. Carmody took the class to a field trip to the farm, Tracey just got bored until she saw a horse. She knew it had a pretty good name, only it was Tinkle. She asked her parents if she could have a horse, they didn't said no, but rather, they tried to let her know the responsibilities to taking care of a horse. It was really hard but just as she was about to give up, instead, she had a great idea. She'll make her very own horse. But this also makes Megan in love with the mechanical horse. Also, this sends Tracey's little sister into the rapids of the river.
Shamus has to join in the country's running race, because it has been a family tradition. Even if he doesn't win, as long as he beats a McConaly. Tracey trains Shamus in the track but she thinks Shamus is too slow. So, Tracey invents the zoom boots. And also, Tracey has to deal with the chores her mom and dad assigns her.
Shamus wants to join the gardening competion and grow the biggest tomato. But he grows his naturally, so, now he's losing hope since everyone else is using chemicals. Tracey puts up the greenhouse in her backyard. But when they idd grew the biggest tomato, they also made a bug as big as a tomato.
