One-Eyed Jack is a purple-tinted Whatnot who is one of the mutinous pirates in Muppet Treasure Island. Though he received his name in that film, the puppet first appeared (sans eyepatch) in The Muppet Christmas Carol, taking on two different roles in the same film. In the opening number, "Scrooge," he plays a vegetable seller (of the Singing Food) performed by Frank Oz. Later on, in "It Feels Like Christmas," he resurfaces as a prisoner with a British accent performed by Jerry Nelson. Although the character's name is One-Eyed Jack, and despite the presence of an eyepatch in Muppet Treasure Island, the puppet does not have any actual eyes as a facial adornment. He made a background cameo in Muppets Most Wanted, appearing when Kermit is sent to the gulag as Constantine in disguise and also appears in the gulag finale next to Blind Pew and Blue Frackle.
