Chapi Chapo is a French short stop-motion series. Created by Italo Bettiol and Stephano Lonati for the production company Belokapi, with music by François de Roubaix, it premiered in 1974 on R(T)F Television (and later on Boomerang) and ran for 60 5-minute episodes.
The show aired on American television in the 1980s as part of Nickelodeon's Pinwheel.
"Chapi Chapo" is a play-on-words with the French word, chapeaux, which means "hats". Both of the main characters wore oversized hats that matched their clothing. The one in red is Chapi (a girl) and the one in blue is Chapo (a boy). Each episode ends with a little dance.
An announcement was made in 2015 that a new Chapi Chapo series is in development. It will be in CGI, and produced by Moving Puppet Studio.
