Happy Valley

Background
This was the production company of TV producers/animators Romeo Muller and Robert L. Rosen. Formed in 1978, the company's specials were co-produced by Murakami Wolf Swenson, mostly in association with Japanese studio Toei Doga (now Toei Animation). After the completion of Peter and the Magic Egg in 1983, the duo split, disbanding Mueller/Rosen Prods. Romeo Muller died of a heart attack in 1992.
