The River of Life

Air date: 2/2/87

When Doc comes into the workshop, he has a surprising look on his face, and then tells Sprocket that he just met a man on the street who could make him $100,000 richer; all Doc has to do is allow the man to dump industrial waste into the limestone caves below the shop. When Sprocket hears this, he wants Doc to not take the deal, because there's furry creatures who live down there. Meanwhile, Boober doesn't feel like going for a swim today. Instead, he wants to do some 'anting' (watching ants). But when he smells something terrible in the water, he tries to go and stop his friends from swimming before they get contaminated. But it's too late, and all the Fraggles, except Boober, fall terribly ill. Boober then goes up to the Trash Heap and tells her the news. Marjorie then tells him that, if there's a problem in the river of life, it gets past into everybody's surface. She then tells him that he needs to go to "Outer Space." The Gorgs' water has been poisoned too, and when they think it's the Fraggle's fault, Boober tells them that it's the Silly Creatures from "Outer Space." Pa Gorg then assigns Boober to go there and straighten things out. But Boober's feeling incredibly helpless, and has no idea how to get the Silly Creatures to stop contaminating the water. Will Boober finally go to "Outer Space" alone and save everyone? Or will Doc take the money?

Beyond the Pond

Air date: 2/9/87

When Red and Gobo are getting ready to have a swim meet, the contest gets cut short when the Knobblies - thick, pink vines - come to the surface of the pond, leaving almost no room to swim. Boober brings some Kolerabi juice by for his friends to drink, but nobody likes it. But when Red dumps the juice on the vines, the vines shrink and die, giving more room in the pond. Boober then rushes back to make more so the swim race can still go on. When Red grabs one of the vines, they give her a vision, with weird creatures saying, "Follow the roots." Red then dives into the very bottom of the pond to find out where the message is coming from, and discovers that the vines are roots to a huge, underwater tree. When Red gets to the top of the tree, she finds five Merggles (mermaid Fraggles); Merboo, Merkey, Mermer, Merple, and Mervin. They are delighted that their message to Red worked, since they're now able to communicate with another species besides themselves. Meanwhile, back at the pond, Boober's Kolerabi juice is being dumped by the bucketload onto the Knobblies, and while Red's celebrating with the Merggles, the branches start dying, and they can't figure out why. Red then tells them of Boober's juice, and they lock Red in a cage, then swim far away before they die. But when Gobo grabs one of the vines up by the pond, he receives a vision to "Stop pouring the Kolerabi juice", and "Follow the Knobblies", which he does. It's up to Gobo to go find and rescue her before the tree dies and the Merggles leave forever.

Gone But Not Forgotten

Wembley's really excited today, because today is going to be his first solo, overnight hike. But while on the way, he becomes trapped in a rockslide, and when he wakes up, he's being comforted by Mudwell the Mudbunny- the rarest creature in the Rock. Mudwell and Wembley have such a wonderful time together, and seem to be great friends. But when Wembley wakes up from his nap later on, Mudwell tells him, rudely, to leave and never come back again. When Wembley returns, he's upset, and the other four make him share his story about Mudwell. Gobo tells him that maybe he should go back and have Mudwell explain, so Wembley goes back, just as Mudwell is lying by a mud puddle. He tells Wembley that he'd like to be friends, but it's time for him to leave. After Mudwell becomes quiet, Wembley realizes that the Mudbunny has died. When Wembley sees his four friends again, he's really sad, so all four of them- and The World's Oldest Fraggle- try to cheer him up but fail. Finally Gobo tells him that, even though Mudwell's gone, there's ways of keeping part of him alive. So Wembley gets an idea, and goes back to where Mudwell passed away, only to discover something truly unique about Mudbunnies.
