The Rock Lobsters are a crustacean band who appeared in Muppets Tonight episode 204. They were booked on the show to perform the B-52's song that shares their name. However, they secretly planned to seize control of the broadcast, as representatives of the Crustacean Liberation Army. They are eventually foiled by Pierce Brosnan and his deadly alarm clock weapon.
The Rock Lobsters were performed by Jerry Nelson (leader), Steve Whitmire (singing vocals), Dave Goelz (Ed), and John Kennedy (female rock lobster).
