I mean, as his name suggests, I knew he was tall, but 8′ 2″ tall? That’s REALLY big.

Big bird is a full-body Muppet. The Muppeteer, usually Caroll Spinney, “is completely enclosed within the costume, and extends his right hand over his head to operate the head and neck of the puppet. The Muppeteer’s left hand serves as the Bird’s left hand, while the right hand is stuffed and hangs loosely from a fishing line that runs through a loop under the neck and attaches to the wrist of the left hand.”
