Boo-Boo Bear is a Hanna-Barbera cartoon character on The Yogi Bear Show. Boo-Boo is an anthropomorphic bear cub in a bow tie, who is a friend to Yogi Bear. Boo-Boo often acts as Yogi Bear's 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 he would say "But Yogi, Mr. Ranger isn't gonna like this," or some variation. 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. However, in the episode "Cub Scout Boo-Boo", Yogi tries to persuade Boo-Boo to become a Boy Scout. Boo-Boo declines the offer, but Yogi corrects him by saying that he will be joining the "Cub Scouts", which Boo-Boo accepts. In the 2010 film, Yogi Bear, he serves as the film's deuteragonist.
