thumb|right|Patoruzú comic: "Andanzas de Patoruzú" Patoruzú first appeared on October 19, 1928, in the Las Aventuras de Don Gil Contento strip in the Crítica newspaper, under the name of Curugua Curuguagüigua; last cacique of the giant Tehuelches, of whom Don Gil becomes tutor. The name was deemed too difficult to pronounce and was soon changed to Patoruzú, after the then-popular candy Pasta de Orozú. Nevertheless, the strip was canceled by the newspaper after only a few days. In 1942 the 12-minute short film Upa en apuros was the first Argentine animated film produced in colour.
