When new Doozertubes are delivered to each Fraggle's cave, they're able to come together for a song even though they're apart.

Gobo brings all the Fraggles together on their Doozertubes to show off their talents, but Wembley can't decide what to do.

Uncle Travelling Matt's adventures in Outer Space lead to Gobo, Red, and the Fraggles connecting with special musical guest Common.

When the Doozers set up a Doozertube at the farm of special musical guest Jason Mraz, he joins Gobo and Wembley for a jam session.

The Fraggles are joined by Neil Patrick Harris, Tiffany Haddish, Ziggy Marley, Alanis Morissette, and more special guests for an epic jam session.
