Translator-Helmets are a commonplace bit of Concavian technology.
Description[]
Coincidentally identical to a novelty hat bought in February of 1954 by Minnie Mouse, Translator-Helmets are small high-tech helmets worn by most Concavians to circumvent their oath never to speak aloud if they ever need to, as it translates their thoughts into spoken English.
Behind the scenes[]
The Translator-Helmets appear in the 1954 story A Fatal Occupation.
