Fraggle Rock - Season 3 Episode 15 : Born To Wander 1987

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.
