These Halloween horrors were all carved out of humble pumpkins by Ray Villafane and his team of professional sculptors who meticulously carved the terrifying characters using spoons and scalpels. Each one takes on average two hours to complete – with the horrifying results netting Villafane, plus colleagues Andy Bergholtz and Chris Vierra, numerous TV appearances each Halloween. This year the team has gone global travelling to Germany, Switzerland and Hong Kong to create their masterpieces.
