Mama’s not doing so well
It was clear to her caretakers: Mama wasn’t doing very well. They expected her to pass away soon, especially because she had started to refuse food. All she did was lie around. They were heartbroken, because she had been such an important part of the chimpanzee colony in the zoo.
They realized that if they wanted to cheer her up and ease her passing, they would have to do something extraordinary.
