A parade is organised through Walmington-on-Sea to commemorate Spitfire Week and, after watching a newsreel, the platoon decide it would be splendid to have a mascot. Sponge farms sheep and the men try to catch his ram but it eludes them every time. Walker provides a goat, a skinny, pitiful creature which eats Mainwaring's £5 note.
Down a mascot, the platoon, Hodges and his wardens, the verger and his Sea Scouts, and the volunteer nurses all march faster and faster to be at the head of the procession until the parade becomes a marathon.
