My friend/ex-colleague finally got a clearer picture of the crocodile in Bulatan park. It appears at the same place. In fact, I saw the croc yesterday also but I manage to see only the nose and eyes only.
So, if you want to see the crocodile at Bulatan Park, it seems that it is no longer that difficult. Click here to see more pictures of the crocodile. He estimated the length of the croc to be about 3-4 feet, ie, about 1 metre. That was my estimate also.
