He voiced all the characters without a script, using a language of noises which were dubbed Pinguinese, a voicing he had developed and used for the earlier Osvaldo Cavandoli's La Linea from 1971 to 1986.
Cavandoli was born in Maderno sul Garda, Italy, but moved to Milan when he was two years old (later becoming an honorary citizen of that city).

Cavandoli initially proposed his work for Carosello, an Italian advertisement break broadcast between 1957 and 1977.
