Hanabiko (also known as Koko) is the famous female western lowland gorilla who is known for having learned a large number of hand signs from a modified version of American Sign Language!! She even met Robbie Williams as she loves to watch his movie! She knows more than 1000 "gorillas signs" and understands about 2000 words of spoken English.
I think either Hanabiko or Koko would be a great name for this pet! Maybe more so Koko if that name is to be added to the list of pets names.
