Herb and Glo

Herb and Glo are a happy, friendly couple of tourists who visit Sesame Street in a 1991 episode. They find joy in everything (and everyone) they see when they travel. From Oscar’s point of view, they're "so friendly, it's scary." When Herb becomes especially happy, he sings out his feelings of the moment which is always punctuated by a very high note. Their relentless good nature becomes irritating rather quickly to each person they meet, thus they’re introduced to the next person who comes by.

Herb is a Pumpkin Anything Muppet while Glo is Lavender.
