Reports circulated during and after the show's run that the talking effect was achieved by crew members applying peanut butter to the horse's gums. Alan Young said in later interviews that he invented the story. "Al Simon and Arthur Lubin, the producers, suggested we keep the method making the horse appear to talk a secret because they thought kids would be disappointed if they found out the technical details of how it was done, so I made up the peanut butter story, and everyone bought it."
