 Their state upon their return to camp prompts the leader "Phonus Balonus" to seek the secret behind the Gauls' seemingly superhuman strength.Phonus selects a volunteer (by means of a single round of musical chairs) to pose as a Gaul in order to infiltrate the village; the unlucky loser is a short, slack-tongued misfit named "Caligula Minus".He is dressed in a wig, false moustache and traditional Gaulish dress and led in chains through the forest as a prisoner, awaiting rescue by the Gauls.
