Calimero is the eponymous character of several animated series.
Creation
He was created by the animation studio Organizzazione Pagot for a series of animated advertisements for Miralanza AVA soap products shown throughout Italy.
Animated series
1972 series
In the 1972 series, Calimero has basically the same appearance as his original Italian incarnation, though sometimes he appears a bit skinnier. He plays with his girlfriend Priscilla and Peter (Piero) tries to mess with him. A lot of the stories somehow incorporate the original Italian shorts.
1992 series
In this series Calimero took on a more heroic role, where he, along with Priscilla and Peter/Piero (who became Calimero's friend in this series) investigate mysteries with the help of new friends, Giuliano (a green chicken, also known as Valeriano), Suzy (a bespectacled girl duck) and Rosita (a bespectacled girl chick, also known as Romi).
2013 series
In the 2013 series Calimero (along with all other characters) is animated in CGI and does not wear a red vest. He moves to a new town (called Belladagio in Italian and Hatchington in the UK English dub) , but he still plays with Priscilla, Valeriano, and Piero on a daily basis and they discover the amazing inventions in the Mill which belonged to Calimero's great grandfather Do Vinci. Suzy and Rosita/Romi do not have main roles like they did in the 1992 series, but they are recurring characters in some episodes.
