Plug, whose real name is Percival Proudfoot Plugsley, is a lanky, gangling character with a large overbite, protruding ears, two buck teeth and a wide nose. On the cover of "Plug" his name is given as Percival Proudfoot Plugsey, although in some earlier strips he is named Claude. Plug's real name is only occasionally used in "The Beano", such as in "Singled Out" when Teacher addresses him by his full name. He is originally known as Pug; according to "The Beano", the "l" was added when Smiffy had one to spare after misspelling "silly".
