The French Muppet characters are Toccata the large Albatross, Mordicus the saxophone-playing blue Grouch, and Trepido (a pink snail). The series was executive produced by Michel Berthier from TF1 and Lutrelle Horne from CTW. The show ran for a total of 80 episodes and ceased production in June 1982. A similarly titled French co-production debuted in 2005, called 5, Rue Sésame.
