Hum Bear is Sally's round stuffed teddy bear. He is the second toy to come to life, thanks to Melody Mouse. he sometimes bumps into to people. He and Melody Mouse tell Sally and Jonathan that toys like themselves like to party, too because toys like themselves are a lot like Sally and that they all have head and shoulders and knees and toes as well as eyes and ears and a mouth and a nose, and they start singing the Head and Shoulders Knees and Toes song to Sally and Jonathan and the two kids join Melody Mouse and Hum Bear singing the song. They all the rest of the song real fast and sit on the floor next to Sally's bed, wiggling their heads and shoulders and pointing to their knees and their toes and fall backards at the end of the song. When they all get right up again, Sally rushes to her dresser asking Melody and Hum Bear that do not expect the kids to go the party in their PJs.
