7 years old, female: Lukuru has been at Lola since she was two years old. Once just a whisper of a bonobo, she has grown into a sweet, gentle big sister. She has recently been promoted to Assistant Mama. She takes care of all the new babies, protecting them from the rougher, naughtier bonobos, comforting them when they cry, and carrying them when they are tired. Lukuru is also something of a Public Relations consultant, since she is always inventing creative ways to engage the visitors, from chasing games to a kind of birdlike song she performs on occasion. She has even mastered the Japanese bow!
