A "Muppet" is a type of puppet created by Jim Henson, known for its unique design and expressive features. Muppets are typically made from soft materials like felt and foam, allowing them to be animated easily. They are often operated by puppeteers who manipulate them from below, giving them life through movement and voice. Muppets gained widespread popularity through television shows like The Muppet Show and movies such as The Muppet Movie. Iconic characters include Kermit the Frog, Miss Piggy, and Fozzie Bear. The Muppets are celebrated for their humor, creativity, and ability to appeal to both children and adults.
