Full-bodied Muppets require the performer to literally step inside them. Big Bird is probably the most recognizable of this type of Muppet. The novelty of Spinney’s claim to the character is what first got the attention of the filmmakers behind the documentary I Am Big Bird: The Caroll Spinney Story. To attain Big Bird’s height, the Muppeteer inside wears shoes with 5-inch heels. He raises his right hand as high as he can above his head to control Big Bird’s head and mouth. His left-hand fits into Big Bird’s left glove.
