Invisible Gorilla. Yeboah has been at London 3 months now but these are still the only photos I've seen of him. He appears to be invisible! Has he been outdoors yet I wonder?
Good point. I've not been for several weeks, so I owe the zoo a visit quite soon. I'll try and find out when I go, but hopefully someone else can update us on Yeboah's status in the meantime.
