Gyro also had an assistant named "Helper" who was essentially a lightbulb attached to a Meccano-style stick-figure body. He never talked, but was fairly useful. Gyro also possessed a "thinking cap" which was a bird nest/house complete with actual bird. When placed upon his head, the hat would, after a short time, exclaim "Cuckoo!" and Gyro would have some random epiphany.
