The Muppets are a group of puppets that achieved worldwide fame in 1976 with The Muppet Show. The characters were created by Jim Henson in 1955 for the television show "Sam and Friends." The Muppets are known for their comedy shows, even alongside famous people/special guest stars.
In 2014, some of the members of The Muppets arrived on Club Penguin Island to invite all penguins to a "trip around the world," being the Muppets World Tour. During that time, players could meet them as sprites in various rooms and perform tasks, which when completed, resulted in items. Costumes of most characters were also available.
