Six is in the gym, playing with a toy car that's controlled by a mat with arrows on it. Four slides down the slide and Six asks him what he thinks of the controller. Four, despite initially being startled, thinks it's great, but then admits he doesn't know what it is. Six refers to the mat device as a "moving mat", and Four asks if it just moves the car. Six says that it moves anything and could probably even move Four, so Four volunteers to test this hypothesis.
It turns out that the mat can move Four, and Six has fun moving him in different directions. Initially, Four finds this exciting, but finds being turned around annoying, especially when the device gets "stuck", causing him to keep turning. Eventually, Six unsticks the mat, leaving Four giddy, and the alarm sounds.
Four feels a bit disabled due to his giddiness, but he still gets to the control room fine, and Agent 17 explains what the problem is: a little girl is trying to read but her book keeps sliding around. Five is sent out and lands on a lamppost.
Five goes into where the girl is reading, and the agents observe the directions the book is moving (left, right, and forwards). Then, in the same house, a boy is trying to draw but his paper slides away, and a woman is trying to eat salad, but her plate moves sideways.
Then, the Shape Japer flies into the kitchen. Five suspects that she is the culprit, but why would the Shape Japer do that? The agents point out that two out of three of the affected objects are rectangular, while the plate is a circle, so perhaps she's favouring rectangles and circles.
Five tells the Shape Japer to stop and she agrees, but starts spinning them instead. She agrees to stop again, but Five isn't sure she means it, and starts to imagine. She imagines the Shape Japer sliding the sun up and down, changing a window's position, and sliding and turning a door on the same house as the imaginary window.
Agent 106 calls in, reporting that the Shape Japer is now moving people. A frightened Three asks where the Japer is and it turns out that she's sliding and turning a cleaner away from some spilled chutney. The agents have an idea: use Six's "moving mat" to steer the cleaner in the right direction.
They connect the mat to the brain gain machine, but Three gets a bit too gung-ho and makes the janitor spin around. Thankfully, Six and the agents set things right and make him go forward, turn to the bucket, go forward again (so he can dip his mop), turn him over, and make him move back and forth to wipe the chutney up.
The cleaner is happy, but then the Shape Japer comes back and starts turning Five around and moving her back and forth. Using brain gain and the moving mat, the Numberjacks and agents give the Shape Japer a taste of her own medicine by controlling her actions.
She flies away, Five comes back (still a bit dizzy), and they show it onscreen. Back at the gym, Three wants to give moving two Numberjacks (One and Two) at one go, but Six is doubtful. It works, and the little numbers enjoy it, but then she accidentally makes them hit the wall, making them dizzy. Six observes that Two looks different when he turns around, but One looks the same. He asks the viewers to find other numbers that look the same backwards.
This episode provides examples of
- Ambiguously Related: The girl and boy seen at the beginning appear to live together, so maybe they're brother and sister, but it's unspecified. Similarly, the salad-eating woman's relation to them is left unstated, but she could be their mother.
- Evil Laugh: The Shape Japer laughs evilly when she's controlling the janitor.
- From Bad to Worse: The Shape Japer starts out moving things around, then she starts moving people around.
- I Don't Think That's Such a Good Idea: At the end, Six is a bit dubious about Three moving two Numberjacks at once.
- In-Series Nickname: Six calls the Shape Japer "the Japer".
- Loophole Abuse: The Shape Japer promises to stop sliding things around... so she spins them around instead.
- Suddenly Fluent in Gibberish: When Five talks to the Shape Japer, the latter says something that sounds like "Quai", yet Five can somehow understand. Apparently, "Quai" means, "I promise to stop doing that".
- Swiper, No Swiping!: When Five tells the Shape Japer to stop sliding things, she does. Unfortunately, she spins things instead and later breaks her promise.
- Talking in Your Sleep: A cat in Five's imagination meows in its sleep.
- Tempting Fate: Three and Six point out that it was easy to convince the Shape Japer to stop sliding things and suggest that Five come home, but then the Japer starts spinning things instead.
- Translation: "Yes": The Shape Japer says, "Quai", which Five translates as something along the lines of "I promise to stop doing that".
- Weird Sun: Five imagines a sun with a face.
