UFO! Host

From Muppet Wiki

The UFO! Host appears in the Dinosaurs episode "We Are Not Alone." The solemn, turtleneck clad dinosaur hosts a television program exploring strange phenomenon and extraterrestrial sightings. Earl Sinclair attempts to use the show to spread the "alien"'s message that dinosaurs must stop polluting the earth. The host's voice and attire are reminiscent of Leonard Nimoy's when hosting the series In Search Of.
