Boo Boo first appeared along with Yogi in the "Yogi Bear" segment of The Huckleberry Hound Show in 1958; when Yogi was given his own series in 1961, Boo Boo went with him. He doesn't mind eating what Yogi finds but he still doesn't like knowing that Yogi steals it. Boo Boo is voiced by Don Messick who also voices Ranger Smith.
