Red's been playing "Princess Gwenelot and the Evil Dragon" lately, and when Gobo tells her she needs to grow up and stop playing make-believe, she happens upon the T. Matthew Fraggle Room, the cavern with the dozens of tunnels that lead to different places in "Outer Space." But when she accidentally spots a huge, blue dragon, it gets lost in Fraggle Rock. She tries to convince Gobo and Uncle Matt about the dragon, but they just think she's played make-believe too much, so it's up to Red to make things right. (thetvdb.com)
