List of breakout characters
Bullwinkle J. Moose was voiced by Bill Scott on Rocky and His Friends (for first two seasons of the series). Although the series was originally named after Rocky the Flying Squirrel, it was Rocky's dim-witted (and much larger) sidekick, Bullwinkle J. Moose, who got most of the jokes while Rocky served as straight man. By 1961, the series had been renamed The Bullwinkle Show, a title that appears for last three seasons of the series.
