Cambria pioneered its patented Synchro-Vox™ system (developed by Edwin Gillette for "talking animal" commercials in the 1950s) with this cartoon. The Synchro-Vox systems combined still animation cels of the characters and live actors' lips superimposed over the characters heads to make the "animation." Producer Clark Haas referred to Cambria's process of limited animation as "motorized movement." Cardboard cutouts of the character sometimes would be moved by hand past the background. To produce Synchro-Vox, the voice actor would be filmed in closeup, with a mask hiding everything but the actor's lips. Heavy makeup was used to ensure that the actors' skin color matched that of the cartoon characters

When in action, rather than animate the character, the cels were shaken, or the camera zoomed to simulate the motion.

This was one of 52 Clutch Cargo adventures produced. Five five-minute episodes combined to make a show or complete story arc. The first four chapters ended in cliff-hangers, with the fifth chapter wrapping up the adventure.
