One of the muppets from Seseme Street who lives in a trash can.
 

Cameo in Zatanna

In the first part of "Pupaphobia", Zatanna admits that she is frightened of puppets (hand puppets like Scarface, not Voodoo Dolls). She is invited to be on the "kid's tv show, that one about spelling and counting" (Seseme Street) for a skit called "The Magic of Numbers". She wasn't crazy about doing the skit, but she decided she had to do it for the kids. She psyiced herself, smiled her sunnist smile, strutted on set....and vomited into the green puppet's trashcan.
