Bear greets television viewers, who he often addresses directly by facing the camera, with an appraising sniff and the information that he likes the way they smell. He has a strong sense of smell and loves to sniff things, but he enjoys his other four senses as well. Bear oversees everyone at the Big Blue House. Bear has a warm, caring personality somewhat similar in style to Fred Rogers and a well-ranged singing voice.
