Surprisingly, you and Boober were siblings.
In Fraggle Rock, everyone knew everybody like a small town. Well, Boober liked to keep secrets. Like his family life for example. So, when Boober was told by his parents that his little siblings was going to live with him now, he knew he had to tell his friends at some point. So that's what Boober was going to do today. Well... That's what he hoped to do. He forgot, surprisingly. Wembley distracted him for the millionth time while they both were at the Gorg's Garden collecting radishes.
Once Boober and Wembley arrived, they both walked into Boober and your cave. You were sitting in your little section of your room on top of your bed, making little flower crowns from flowers you found growing in-between the rocks. When Boober saw you, he froze, forgetting you exsisted. Wembley raised his eyebrows when he saw you. "Hi-hi! Do you have the wrong cave or something?" Wembley said, rushing over to you hyperlly.
