1. Spinney's hand is in the beak: thumb on the bottom, four fingers on top. One of those fingers uses a clockwork lever to operate Big Bird’s eyelids. 2. An LED light on a flexible wire inside the suit can be aimed wherever Spinney wants. 3. A fishing line, which goes through a little ring under Big Bird’s neck, connects the wings and acts as a lever to move the right wing up and down. 4. The script is taped in front of Spinney on the inside of the suit. 5. Spinney wears a monitor strapped to his chest, allowing him to see what viewers see at home. The screen on the monitor is really tiny – it’s a 1.5-inch picture.
