Koko the gorilla amazed the world with her ability to use sign language. When she chose a kitten named “All Ball” as her companion, their bond showed the purest form of love.

KOKO & PENNY READ "KOKO'S KITTEN" — PART 1: THE BOOK In this video from KokoArc, it’s 1988 and Koko is very eager to look at the book “Koko’s Kitten." This book was first released in 1985 by Scholastic. Koko looks at some of the photos with Penny and signs about them. She then takes the book to higher ground to examine it on her own — an expression of her autonomy. She also demonstrates her creativity and enthusiasm by using some signs simultaneously — like “Gorilla-Animal” and “Book-Hurry." Kok
