There are Monkeys  on Penang Hill.  
It’s a jungle out there but Dave can’t see any Monkeys.

 
A quick rest on the long hunt. Little legs get tired fast.

  
That is not a Monkey; that’s a postbox.

 
That is not a monkey either; that’s Dave swinging on a vine.  

Dave did see a monkey but it was to far up a tree to photograph. The bats Dave saw moved to fast to photograph and the black squirrels were pretty quick too!
