For once, Roscoe's letting it all hang out.




Where you lead, I will follow...best friends Suryia the orangutan and Roscoe the Blue Tick hound are due to appear on the Oprah Winfrey show later today.




Suryia's in pensive mood while Roscoe's oblivious.




Bubbles is a four-tone African elephant and a favourite among visitors.




The two mates see the funny side of most things.




There's always time to chill.




A dog's not just a man's best friend, he's an orangutan's too.
