Rumcajs is one of a number of characters created by famed author and poet Václav Čtvrtek to be adapted into a Večerníček production. Dressed in his trademark red hat, white shirt, and red pants, he’s a Robin Hood-like character who lives in the forest with his wife Manka and son Cipísek. The series, directed by Ladislav Čapek, is notable for its fluid animation style (by Radek Pilař, who also provided the illustrations for Čtvrtek’s stories), particularly impressive for the era.
