Boo-Boo Bear is a Hanna-Barbera cartoon character on The Yogi Bear Show. Boo-Boo is an anthropomorphic dwarf bear who wears a blue bowtie. Boo-Boo is Yogi Bear's constant companion (not his son, as sometimes believed), and often acts as his conscience. 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 – 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.
