How much does koko weigh?

As an AI language model, I don't have real-time access to information about the weight of specific individuals. Koko, the famous gorilla who was known for her ability to communicate using sign language, passed away in 2018. At the time of her death, Koko was estimated to weigh around 200 pounds (91 kilograms). However, please note that this information might be outdated, and I recommend checking more recent sources for up-to-date weight information.
