Gwildor comes with one accessory. His time travel device, the Cosmic Key, doesn't look exactly like it did in the movie. The red top can spin on the silver handle, in the film the key would spin and make musical sounds when it was activated.
Gwildor decided to go back to the drawing board after the Cosmic Key turned out to not be very dependable. One day he slipped off the toilet and hit his head on the sink and when he awoke he invented the Flux Cosmic Capacitor.
