"Rock-A-Bye Bear" was completed in May 1950, but didn't release until July 1952 after Tex Avery took a break from MGM. He was being replaced by Dick Lundy, who also worked for Universal's Walter Lantz and Disney shorts before the cartoon released until Caballero Droopy (1952) and The Little Wise Quacker (1952). Later, Avery returned from MGM in late 1952 since this short made.
Big Bear Lake, a popular mountain resort destination, is where the main character resides. It is a year round location, with snow providing plenty of winter scenery and sporting options.
