Four, Six, and Three are in the Cosy Room. Three is looking at her beautiful things, Six is reading, but Four is in a bit of a bad mood and thinks Three should share her things. She agrees, but after giving three of them in a row to herself, Four calls her selfish. Three tries to justify herself by saying that they're hers and they'd be "sad" if she gave any away. Four sulkily says, "They'd probably enjoy peace and quiet" and Six agrees. Three maintains that she can't share her beautiful things. Four says that she's just incapable of sharing in general but Three disagrees and asks to borrow Six's buddy blocks. He reluctantly agrees and she gives Four one block and herself five. Four admits that they are technically shared between them but it's not fair sharing and being fair is the whole point of sharing. He demonstrates fair sharing by giving himself and Three three buddy blocks each. Three is bored by Four's demonstration and Six grumpily asks for peace and quiet, but then the alarm sounds.
Agent 28 reports a problem with people on a beach: some sandwiches teleported from a girl's plate to a boy's, leaving her with none and him with them all. He tries to put them back, but they teleport back to his plate. Six decides it's his turn to do the mission and Three huffily accuses him of being unfair.
After being launched, Six observes a boy's spade teleporting to a girl, leaving her with two spades and him with none. Just like with the sandwiches, it teleports back when she tries to give it back. Agents 101 and 85 sum up the problem: things aren't being shared fairly, and whenever they try to be fair, it goes back to being unfair. Six then observes green slime on one spade, signifying that the Problem Blob is involved. They then see him nearby.
Agent 33 tells the Numberjacks in the control room that the Problem Blob has been causing trouble all over the place. For example, a gardener's plants have all moved into one pot. The Blob then moves into a store, where he makes all of a woman's shopping bags move into one hand, causing her to fall over from the unbalanced weight. Then, the blob makes some kids playing a soccerlike game on the beach play five against one. Five then imagines a bull's horn moving onto another bull, two wheels from a car moving onto another car, and all of a clock's hands moving onto another clock.
Three and the agents fire up the brain gain machine, repeating, "share things fairly!" and "fair shares!" to power it up. Six uses the brain gain to make all the things fair, but the Problem Blob then blobs some flippers, leaving one child with five, another with one, and a third with none. Four and Five have forgotten how to share fairly, so Agents 101 and 33 tell them to give them all one each, one at a time. Three integrates this idea into the brain gain, which is used to share the flippers fairly.
The Numberjacks don't know how to deal with the Problem Blob, but the agents have a suggestion: share his blobs of slime fairly until there is no slime left. Six decides to share them between the blades of grass. This works, and the Problem Blob shrinks and disappears.
Six comes back and they recap the mission. Later, Six reads to Four and Two and Five reads to Three and One. Seven and Eight then enter, wanting to join in with the reading. Five asks the viewer how many groups would be in each reading group if they were being shared fairly.
This episode provides examples of
- An Aesop: If you don't share fairly, you might as well not be sharing at all.
- Beach Episode: Downplayed. Only Six goes to the beach and it's not to have fun.
- Breaking the Fourth Wall: In this episode, it's Five who talks to the viewer.
- Catchphrase: Six mentions that "sharing did the trick."
- Incredible Shrinking Man: When the Problem Blob runs out of slime, he shrinks before fading away.
- Out-of-Character Moment: In other episodes, Six handles Four and Three's bickering by acting as a level-headed, but Cool Big Bro-sort of mediator, but in this episode, he's either trying to ignore them or just angrily snapping at them.
