Flea, the bassist for the band Red Hot Chilli Peppers, is a big fan of Koko the Gorilla, and the Save the Gorillas campaign. Koko and Flea have hung out before, and this time, Flea brought along his guitar. Flea began playing for Koko, and after listening for a little bit, Koko decided that it was her turn. After taking the instrument from Flea, Koko strummed it several times, listening intently to the noise it made. Credit: YouTube/kokoflix
