The two Fraggles stared at the large bridge, trying to find a way to open it, but they couldn't figure it out. The door didn't have a doorknob or a handle.

"How do we open this door, Madam Heap?" Gobo asked.

"You will need four keys," Marjory said. "And it's obvious Lilith hid them, darn her. On the other side of this door is a labyrinth that you must work your way through, and once you find your way through, you will be able to return to Fraggledonia. I have a friend there, Merrow. He was also a Fairy, but Lilith stripped him of his powers. He should be able to help you."

"Is this one of the keys?" Gobo asked, picking up a strange metal object, and holding it up to the book. It was a circle that had an arrow on it.

"That's it," Marjory said. "Now all you have to do is find the other three."

"Madam Heap," Gobo said, "before we do, do you think you can answer a question for us?"

"What's that, little Fraggle?"

"Why do you think Lilith has a picture of Wembley's mother in her cave?"

"I'm sorry, but I don't know the answer to that. But perhaps you will find out as you continue your journey."

Gobo sighed, and crossed the bridge again, looking for more keys. Lou followed him.

"Gobo, does Wembley's mom live in the Rock?" she asked.

"Not anymore," Gobo said. "She used to, but one day, she left, and never came back."

"Why?"

"I don't really know. One day, when I was eight, and Wembley was five, Wini came to Uncle Matt, told him she was going to help Mokey's mom and Red's mom gather radishes, and asked him to look after Wembley for her. Uncle Matt asked when she was going to be back, but she never answered. Later, we ran into Darcy and Cerise, and Uncle Matt asked where Wini was, and they said they hadn't seen her, and when he brought up that Wini told us she went to gather radishes with them, they said they hadn't been to the Gorgs' garden that day, and nobody had seen Wini since she dropped Wembley off with Uncle Matt. And nobody ever saw her again."

"You mean she abandoned Wembley? Just like that?"

"That's what Uncle Matt thought, and so did Cerise. Boy, was she mad! Matter of fact, nearly the entire Rock thought Wini just dumped Wembley with us and left. For a long time afterward, Wembley kept asking where his mother was, and when she was coming back. You should have heard Marlon's mother talking about it. She said Wembley was a product of a one-night stand, and nothing more than an accident, since Wini never got married, which I didn't know until years later. She also said Wini never wanted him to begin with, and never loved him at all. And she said that right to Wembley's face, too!"

"That's terrible!"

"I know. The poor little guy was crushed. I didn't think we would ever get him to stop crying after that!"

"Didn't the Storyteller know why Wini left?"

"I don't know if she did or not. For years, Wembley kept asking her to tell him about his mother, and she always told him the same story. She just left and never came back. Finally, Wembley gave up on it after a couple of years, and nobody's really ever mentioned it after that. I think everybody's forgotten it at this point. And if they haven't, they've never brought it up. They were just willing to accept that Wini abandoned him. I think Wembley accepted it as well, but he still misses her."

"Do you think Lilith might have something to do with Wini leaving? After all, she did have that picture of her in her cave. Or house. Or whatever it's called."

"I don't know. I guess the only way to find out is to continue."

Once Gobo and Lou found all the keys, they stuck them into the door. Three of the keys turned red when they did, and the door was still stuck. Gobo turned one of the keys, and another one turned along with it.

"Oh brother, another puzzle," Gobo groaned. "I hate puzzles like this!"

"Me too," Lou sighed. "Let's just get it over with."

Gobo turned another key, which turned all four keys. When he turned the third key, three of the keys moved. The fourth key didn't move any of the other keys, which relieved him, but it didn't make him feel any better. He just continued turning the keys until they were all in their correct positions. Once he figured it out, the door opened.

"Last one in's a rotten radish!" he called, and dashed inside. Lou rolled her eyes, and followed.

On the other side of the door, as Marjory had said, was a dark labyrinth. The two Fraggles began walking around it, trying to figure out where to go. They knew if they found their way to the other side, they would be back to the mortal world.

"I hate labyrinths," Lou said. "I always feel so lost in them."

"I know what you mean," Gobo said. "I always feel like I'm going to run into monsters in them. The Storyteller once told me this story about a goblin king who made Silly Creatures solve his labyrinth. The only one who did was a Silly Creature who wished the goblins would take away her baby brother, and she had to solve the labyrinth to save him."

"You don't think we'll find anything like that in here, do you?"

"I don't know. But I'll let you know. Actually, I think I saw the Goblin King once, on the box the Silly Creature that lives in Outer Space watches. He was surrounded by goblins, singing about a magic dance or something like that. Go figure."

Lou nodded, and continued following Gobo down the tunnels of the labyrinth. While they were walking, they came across torn up pieces of paper. When they put them together, a map appeared.

"Just what we need!" Gobo shouted. "Come on, Lou!"

Gobo and Lou used the map to get down the various corridors. Luckily for them, there was a small dot on the map that moved whenever the two Fraggles did. Gobo figured that dot was supposed to be them. In one dead end, they came across a barrel, and weird looking peg.

"I wonder what's in this barrel?" Lou asked.

"I wonder where this peg goes?" Gobo asked. "Forget the barrel, Lou. Let's keep going."

Lou shrugged, and followed Gobo. After a few more turns, they came across a large door with a hole in the middle of it. Gobo took the peg, and stuck it into the hole, which unlocked it.

"These Fairies use weird keys," he said. "We'd better keep going."

Lou nodded, and continued to follow the orange Fraggle. As they were walking, they came across some more barrels, as well as another metal key, like the ones they had to stick in the door earlier. Lou picked it up, and put it in her pocket. At the end of another hall, Gobo found a hammer, and picked it up.

"You never know what you'll need in a maze," he said.

The two Fraggles continued along. Along another tunnel, they found another key, and another door.

"I hope this is the last of them," Gobo said, walking up to it. Then he and Lou got a good look at the door, and groaned.

"Oh no!" Gobo shouted. "It's just like the door where we entered! And we've only found two keys!"

"Maybe the other three keys are in the barrels," Lou said. "This hammer should break them open. Let's go!"

Lou took the hammer from the orange Fraggle, and ran off. Gobo sighed, and ran after her. After all, he still had the map. The first barrel they smashed open didn't have anything inside of it, so they went to the next one. The second one hid one of the keys they needed, as did the third one. The fourth one was empty. The last barrel held the last key, and the two Fraggles ran back to the door as fast as they could.

"How much you want to bet this is going to be just like the door we came through?" Gobo asked, as he and Lou placed the keys into the holes. When they did, they all turned red, signifying that they weren't in their correct positions.

"What'd I tell you?" Gobo sighed, and immediately got to work turning them. When he finally got the right combination, the door opened, and he and Lou raced through it, leading to a wooded area.

"We did it!" Lou shouted. "We're back in the mortal world!"

"And this path leads right to Fraggledonia," Gobo said. "Now all we have to do is find out where this Merrow is."

"And hope he can help us," Lou said.

Gobo nodded, and he and Lou ran through the woods, hoping to find this Merrow that the Trash Heap mentioned.
