While Ma and Pa are on their afternoon walk, Wander McMooch, a greedy real-estate developer, comes on the scene and swindles Junior into selling the castle for ordinary peas that he claims are Peas of Powerlegend stating that if a Gorg plants one, it'll turn into a Gorg bride at dawn. Mokey and Red, who have been captured, decide to help Junior get back the castle in exchange for their freedom. The plan fails, but when McMooch mentions his distaste for Fraggles, Junior uses this to his advantage and scares him away.
This episode contains examples of:
- Birdcaged: Junior traps Red and Mokey in one.
- Community-Threatening Construction: Although the Fraggles and the Gorgs are enemies, they depend on each other. If McMooch tears down the castle and destroys the garden, it will mean not only homelessness for the Gorgs but starvation for the Fraggles.
- Con Man: McMooch, who tricks Junior into selling the castle for ordinary peas that he claims are Peas of Power.
- "Could Have Avoided This!" Plot: If Junior had realized the Peas of Power were only a legend, he wouldn't have sold the castle to McMooch, and the whole mess wouldn't have happened.
- Eek, a Mouse!!: McMooch, who flees at the sight of the Fraggles.
- Fantasy Sequence: Junior plants a pea McMooch sold him and sings "Dream Girl Lover" while imagining it growing into a beautiful Gorg princess.
- Friendly Enemy: Mokey, although a prisoner of Junior's, tells the latter he's been tricked and helps him.
- Four-Philosophy Ensemble: Inverted. Mokey and Red fill in three of these. Mokey is the Optimist, trying to see the bright side. Red jumps from being the Cynic to the Apathetic.
- Greed: Junior, Red, and Mokey try to get the castle back by playing on McMooch's. The Fraggles slip rhinestones from Ma's sewing basket into the pods of a full-grown pea plant. At dawn, Junior opens a pod and tells McMooch that the peas grew diamonds instead of a bride. McMooch nearly calls off the deal, but he just so happens to have brought a jeweler's glass with him.
- Literal-Minded: When Pa complains that the castle is falling apart and adds, "If I could, I'd sell this place," Junior takes it literally and sells the castle to McMooch.
- The Mark: Junior.
McMooch: No one is easier to do business with than a Gorg. They're all dunderheaded lummoxes.
- Only Sane Man: Junior actually handles getting rid of McMooch pretty well, unlike his parents, who make no attempt whatsoever.
- Pinky Swear: When Junior sells the castle to McMooch, they take the Solemn Oath of the Gorgswhich, according to Pa, cannot be broken for any reason.
- Real Estate Scam: McMooch wants to buy the Gorgs' castle so he can tear it down, level the land, and have a village built on it.
- So Proud of You: Ma and Pa say this to Junior after he and Red and Mokey scare McMooch away.
Ma: Oh, son of mine, you have saved the ancestral home of the Gorgs!
Pa: Junior, I never thought I'd live to say this, but that was brilliant.
- "Well Done, Son!" Guy: Junior wants to get some Peas of Power so he can prove to Pa that he's not a dunderheaded lummox.
- Widow's Weeds: Ma dons these, comparing the selling of the castle to a funeral.
- Win Your Freedom: Junior agrees to free Red and Mokey if they help him get the castle back.
- Worthless Yellow Rocks: McMooch offers Junior a sack of gold in exchange for the castle, but Junior has no interest in gold. He'd rather have Peas of Power.
- You Are Better Than You Think: Mokey assures Junior he's not a dunderheaded lummox and that he can get the castle back if he makes use of what he has.
Mokey: You may not be the most intelligent creature in the whole world, but you have many special qualities.
Red: Oh, boy...!
Mokey: Just focus on those qualities and use what you have.
