The Fearless Four

The Fearless Four is a 1997 German animated musical film loosely based on the folk tale of the "Town Musicians of Bremen" by the Brothers Grimm, about four funny animals that all have one thing in common: they want to sing, but can't for assorted reasons. Combining traditional animation with computer animation, the film was produced by Munich Animation and released by the German unit of Warner Bros. under the Warner Bros. Family Entertainment label. Producer Eberhard Junkersdorf won a Bavarian Film Award in 1998 for "Best Production".
