When Marjory falls ill, Boober is called to a special task: venture into the deep mountain of trash in order to heal her.

Jim Henson's fun-loving and musical Fraggles - Gobo, Red, Wembley, Mokey, Boober and new Fraggle friends - have returned for all-new adventures about the magic that happens when we celebrate and care for our interconnected world. It's the Night of the Lights, the most Fraggily holiday of the year, and the Rock is filled with songs and cheer. When Jamdolin encourages Wembley to make a special wish, the Fraggles head out on an adventure to find the brightest light and, maybe, the true meaning of the holiday.
