Lo-Co is a caricature of Cee Lo Green that appeared in the video for "All I Need is Love". Lo-Co made his debut in a The Voice-style rotating chair after Green dropped in on the Muppets' holiday party.

He also appeared with the Muppets on both Good Morning America and The Voice on November 27, 2012. In one speaking appearance, Lo-Co was performed by Bill Barretta.^[1]

His name is a pun on the Spanish word "loco," meaning "crazy."
