Plot summary
Skeletor is angry that his minions, Evil-Lyn and Tri-Klops, have once again managed to fail in carrying out one of his evil schemes. They were supposed to be planting a globe under the royal palace, but He-Man caught them. Skeletor sends them back out to try again.

Meanwhile, at the palace, Teela gloatingly tells Adam that his father wants to see him; turns out Adam's young cousin Jeremy is visiting, and Randor needs the prince to watch him. Jeremy immediately proves himself to be a spoiled and annoying brat, insulting everyone he meets, messing with Duncan's new rock softener device, and wrecking stuff in the lab. Jeremy has successfully proven that he needs careful watching; so naturally Adam ditches him and leaves him in the (in)capable hands of Ram Man. While Adam and Duncan are testing the rock softener out in the field, Jeremy blackmails Ram Man into potential brain damage, then hops on a sky sled (something Adam expressly told him not to do) and ends up with Ram Man hanging off the back. Evil-Lyn and Tri-Klops return in the Basher in time to watch all of this play out (though they miss Adam turning into He-Man to save the boy). Lyn decides she will have it made in the shade if she can forget about the whole globe plan and grab the rock softener, which will give her and Tri-Klops easy access to Grayskull (and cut Bonehead out of the picture!).

Back at the palace, Adam tries to talk some sense into Jeremy and warn him that his heedless actions could get other people hurt. Ignoring this prophetic warning, Jeremy escapes from his room and goes to the market, where he nags a shopkeeper into letting him try a magneto-boomerang. A mysterious and friendly old lady lends him a coin to buy the boomerang, then asks a favor of Jeremy: could he play a prank on her old friend Man-at-Arms? She just wants his rock softener gadget . . . to no one's surprise except Jeremy's, this is Evil-Lyn.

When the heroes find the rock softener is missing, they jump to the correct conclusion, and Jeremy 'fesses up to his misdeed. He-Man and Duncan race off to Grayskull, unaware that a guilty, chastened Jeremy is following them on a robot horse. At the castle, the bad guys learn from a robot minion that the globe from the beginning of the episode is being kept inside, so they remotely activate it. While it grows and grows, messing with the Sorceress's feng shui, Lyn uses the rock softener to break down the Jawbridge. The heroes arrive, but through a mishap He-Man ends up falling in the beam of the rock softener! Duncan, trapped by a vine spell of Lyn's, is equally incapacitated. Most conveniently Jeremy shows up and has just the thing to snatch the device back from the bad guys: his magneto-boomerang. Duncan uses his gadget to reverse the effects of the beam on He-Man, who easily just picks up the bad guys and carries them off so that Duncan can stick them in his porta-prison.

But wait! The Sorceress's floaty head lets He-Man know there is one more teensy problem to take care of: the ginormous globe. "No magic can stop it," says Sorceress, "only your strength can." So He-Man pushes like a lady in labor, and somehow manages to shrink the ball. With a little anti-gravity lift from the Sorceress, he gets to the window and punts the thing off into space, where we can only hope it won't start growing again, because what would stop it?

End with a Joke: Orko throws the magneto-boomerang to a departing Jeremy; rather than getting to its intended target, it flies back into a window of the palace, producing sounds of great distress from inside. Then somehow it comes back out again and chases Orko, which amuses everyone but Orko.

Wayward child learns a valuable lesson: This episode is the first in this He-Man trope. You could include MU010 in this list, though the lesson there was learned by Ileena, who wasn't really a child.
