LOS ANGELES (AP) — It’s time to play the music. It’s time to light the lights. It’s time to stream the video.

The Muppets are appearing in skits and other online videos with several YouTube stars, including Mike Tompkins, Lindsey Stirling, Elliott Morgan and John and Hank Green.

The videos were filmed on location at YouTube Space LA, a new production facility operated by the streaming service in West Los Angeles.

“It’s not every day that our YouTube creators get to work with the world’s most famous frog, the world’s most beautiful pig, a stand-up comedy bear and the drummer of the almost-legendary band, the Electric Mayhem,” said YouTube Space LA head Liam Collins in a statement.

The collaboration kicked off last month when Gonzo, Rizzo and Kermit doppelgänger Constantine popped up in a detective-themed video on YouTube’s VSauce3 channel. The video has already amassed more than 1 million views.

Other upcoming appearances will include Dr. Bunsen Honeydew and Beaker answering science-related questions on the Mental Floss channel and the whole Muppet gang performing “Pure Imagination” with violinist Stirling on her channel.

“The Muppets have been entertaining and inspiring YouTube audiences for several years, and we are thrilled to re-engage current fans while capturing new ones through these exciting collaborations,” said Muppets Studio vice president Debbie McClellan.

YouTube is celebrating its 10th anniversary throughout the month of May. The streaming service opened with its public beta launch in May 2005.
