Junior Gorg's only friend is a huge radish named Geraldine, a fact which he discovers thanks to Mokey.

Gobo's come down with the Pebble Pox, so it's up to Boober and Wembley to go to the Cave of Shadows to get Gobo's cure. However, Boober's not too fond of the idea, and shares his worries with Wembley along the way. Before long, Wembley comes up with a bad case of the Pebble Pox, too. Will Boober leave his sick friend behind and ditch the journey, or will Boober put his germ-worries aside to help his friends?

Philo and Gunge are sick and tired of being around Marjorie, so they decide to go off and find their home. The only problem is, they don't know where they originally came from. After a failed attempt to live in Mokey and Red's room, they travel far away, were caught and made slaves of Wander McMooch, the Trash Heap's biggest enemy. When the Fraggle Five see that Marjorie is becoming weak without her rodent duo, it's up to Gobo, Mokey, Wembley, Boober and Red to save Philo and Gunge from McMooch before it's too late.

Red absolutely loves her radish bars (which are the equivalent of Pop-Tarts in our world). So when she sees that whenever she wakes up from sleeping that her bars are missing, she sets out to find the crook, which leads her to think her roommate Mokey stole them. She also gets Gobo to hide in a hole outside her room to watch and see if it really is Mokey; after Gobo gets distracted from reading a postcard, the bars go missing again, but Gobo claims he didn't see anything. So finally she gets Wembley to stay the night with her to catch the thief, and what Wembley finds ends up being quite surprising.

Mokey's been making too many promises lately; most notably, she was supposed to knit a tarpaulin for the Trash Heap before the next big snow. But she ends up being too late, and when she sees Philo and Gunge mourning over the frozen Marjorie, she decides she has to fix her mistake. When she overhears the Gorgs need to throw out some yucky, hot soup, she along with the help of Gobo go into the Gorg's castle to find a way to get the soup on the Trash Heap so she can thaw out.

When Gobo, Red and Wembley are searching for unique items, Wembley comes upon an old green bottle. He takes it back to his cave, and while he's polishing the bottle up, a genie appears. Wembley can hardly believe his luck, but this genie has his own agenda. He destroys all the items Gobo and Red found, then he scares Boober half to death by making his laundry look like ghosts. Gobo says he needs to get rid of the mean genie, but the genie says he needs to stop letting Gobo boss him around. Later on, Wembley decides Gobo was right, and they create a plan to get the genie back in the bottle, then bury it. The plan works, but Wembley feels sorry for the genie, and lets him out. Later on, when Gobo's trying to show everyone the bottle, he accidentally breaks it, but Wembley confesses he let him out. The genie shows up again, and turns all the Fraggles into something that looks like a Fraggle army. It's up to Wembley to stick up for himself to make things right again.

It's time for the annual Beanbarrow Race, and it's Gobo and Wembley vs. Red and Mokey. But when Mokey gets delayed, Red ends up having to do the race with Lanford, Mokey's annoying plant. As they're racing, Red and Lanford get lost at Table Rock Cavern which is where the Clinging Creepers live. When the Clinging Creepers start to attack them, Red and Lanford must work together in order to escape.

Boober's been testing belouviouses, which are the part of a Fraggle's tail that flares up when scared. And when he tests Wembley's, Wembley wants to get even, so Philo and Gunge give him ideas on how to test his belouvious back. When hiding in the laundry and shouting "Boo!" doesn't work, he goes with an elaborate plan of setting up scary masks, spiders and snakes. Wembley goes back to Philo and Gunge to tell him of what he's set up, Marjorie tells him that when the boys tried scaring her, she nearly blew up. Wembley misunderstands this, and tries to go back to tear down his plan before Boober shows up, but he's too late, and thinks that Boober's blown up. Did Wembley go too far?

The Storyteller's having a story-telling session in Gobo's room, so Gobo decides that he wants to hear about Uncle Matt's first big journey. We see a flashback of little Matt- who's dressed like Gobo is now-with his Uncle Gobo, who thinks that his nephew Matt is annoying and clueless. Back then, Fraggles either ate mushrooms or Doozer constructions, but when the mushrooms run out, Uncle Gobo and Matt try to find some food. However, Matt causes a rock quake, and breaks Uncle Gobo's leg. So Matt goes off by himself to find food, and as he's wandering, a rock slide occurs, and when it's over, Matt finds a hole out into the Gorg's Garden. He goes out to explore, scares Ma and Pa Gorg, and brings back to the Rock a radish, which Matt thinks is a shiny red boulder, thus giving the Fraggles a new food source.

Mokey and Red are putting on a puppet show and on their way to the production, Mokey hears the cries of a strange creature named Begoony, a magical fluffy critter who clings himself to Mokey and wants all of her attention. But when Mokey's torn between helping Begoony and putting on their show, Begoony puts a curse on her that makes her shrink, and then Begoony places her in a dollhouse. Mokey must find a way out and teach Begoony what being a friend means.

Mokey really, really wants to be a part of the Secret Society of Poohbahs, even though Red keeps telling her it's just a silly club. Then one day Mokey gets a letter saying that the Poohbah's would like to see her and find out if she's worthy of being a part of the club. She tells Red of her invitation, only to find out that she wasn't supposed to tell anyone about it. She goes back to find out if she can be a part of the society, but when a member called the Mind-Reader knows that Mokey told her roommate of the invitation, she's immediately rejected, but the Beggler Beg and the Vanguard (who look an awful lot like Gillis Fraggle and Convincing John) say that, if she brings her roommate to verify that Mokey's legit, she can be a Poohbah. Mokey gets all worked up about this, but when she brings Red back so she can be a Poohbah, Mokey finally learns not to take anything too serious that these Fraggles tell her.

It's winter time in Fraggle Rock, and Cantus arrives to help the Fraggles celebrate the Festival of the Bells. However, Gobo's holiday spirits aren't up and he's forgotten the true meaning. So to make this holiday extra special, he decides he's going to find the Great Bell of Fraggle Rock and bring it back before the celebration begins. But the Rock grows colder, and as Red, Mokey, Boober and Wembley wait, they grow closer to becoming frozen. Cantus goes to find Gobo and bring him back, but Gobo's still wanting to bring the Great Bell back. Will he be able to bring the bell back before his friends freeze? Or will he finally understand the true importance of the Festival of the Bells?

Gobo finds the legendary "Grapes of Generosity", mystical fruits which are rumored to compel anyone who eats them to share them with others. However, when Gobo brings them back, he ends up eating them and keeping them all to himself. Before long, Gobo becomes weightless, and tries to hide it from everyone else. But when he hears that Red climbed to the very top of the Great Hall, it's up to him to get Red down safely, and finally admit to everyone that his own problem was caused by being greedy.

Red and Wembley decide they're going on an adventure out in the Gorg's Garden today. At the same time, Ma is trying to get Pa and Junior to clean the basement, which is something that they really don't want to do. Junior catches a fluffy little creature named Skinfrith, and then Red and Wembley set him free so they can have some fun. But what they don't know is, this Skinfrith is a magical creature that can change into anything that someone can imagine. And before long, Skinfrith gets into the Gorgs' basement, and Ma thinks there's a terrible beast inside, which is what Skinfred turns into. Wembley and Red sneak in to save their new friend, but they need to convince Ma Gorg, who's trapped in the basement with them, that Skinfrith isn't all as bad as he seems.

Pa Gorg decides to rid his and Ma's "Kissing Rock" of Fraggles once and for all with the Boredom Juice that Junior found, but things go horribly wrong.

Gobo finds out about Uncle Matt's Secret Rules for Exploring through a postcard, and decides to open up a school for explorers. On his first expedition, he- along with Red, Wembley and Mokey- must travel to the Hole To Who-Knows-Where. Gobo becomes so fixated on the rules that he starts to disregard common sense, and of course, he and Red go at it again. Wembley and Mokey start to agree with Gobo's rules, but before long, they both side with Red. Gobo decides to go find the Hole To Who-Knows-Where by himself, not knowing that he is still tied on to Red. When Gobo and Red fall through the Hole, Gobo needs to use logic to get back home.

It's about to rain, and Ma wants Pa to fix the hole in the roof before it starts to pour. At the same time, Boober and Mokey are out getting radishes, and when Ma accidentally picks Boober up, he loses his hat. Boober's too afraid to go back out there, so Mokey goes out by herself to get the hat. Meanwhile, Ma's having a terrible time getting Pa to fix the roof, because he's too scared of heights. Will Pa get over his fear and fix the hole in the roof before the rainfall?

Gobo feels as if he's done it all and wishes there was someplace he could explore. But when he hears that the Gorgs are going on a vacation, he thinks his problem is solved, and decides to map the inside of the Gorg's castle. So she gets Boober and Mokey to help scare Gobo, who's got Wembley by his side for the overnight stay. But when the Crown Jewel becomes missing, Junior gets scared and thinks somebody's in the castle. When Gobo and the gang reveal themselves to Junior, Junior later thinks that there's a real thief outside. Junior must work with the Fraggles to catch the jewel thief in order to prove to his parents he's mature enough to watch over the castle.

When Cotterpin Doozer hears that Gobo is the bravest Fraggle in the Rock, she gets him to help her find the Cavern of Lost Dreams, which is where the original tower was built. When they get there, the remaining two Doozers, Yeaster and Crusty, don't want to come back. Will these two Doozers finally accept the changes that have occurred and move back to the Rock and help build once again?

It's Joke Day in Fraggle Rock, and Boober's trying to get out before his friends find him and make him participate in the holiday he hates. But before he leaves, a huge purplish-pink glob rolls into the Great Hall. Boober ends up meeting Cotterpin Doozer as well, and the Doozers are on their way to start building near the Blob. However, the Glob starts to eat the Doozers, one by one, and soon enough, Cotterpin's inside the Glob too. Even though a part of Boober really just wants to run away and pretend it isn't happening, he's forced into action and must find a way to set the Doozers free.

It's time for Rock Hockey, and Red's especially excited because her idol, Rock Hockey Hannah, is coming to watch her play. Her excitement's cut short, however, when she injures herself.

So she decides to fool Feeny Fraggle and takes his place as goalie. But is playing the game to impress her hero worth the risk?

When the Architect Doozer is teaching some younger Doozers about the great Doozer king (who looks a LOT like Gunge) Gunge wanders in the middle of the teaching session while looking for the M'Geecky vines for Marjorie.
