Boo-Boo Bear is a Hanna-Barbera cartoon character on The Yogi Bear Show. Boo-Boo is an anthropomorphic bear cub who wears a blue or purple bowtie. Boo-Boo is Yogi Bear's constant companion, and often acts as his conscience.[13] He tries (usually unsuccessfully) to keep Yogi from doing things he should not do, and also to keep Yogi from getting into trouble with Ranger Smith[14] - often saying, "Mr. Ranger isn't gonna like this, Yogi." It is not readily apparent whether Boo-Boo is a juvenile bear with a precocious intellect or simply an adult bear who is short of stature.
