Our Visitor - Yikes!

Matthew 7 years old & Isaac 9 years old came pounding on my door one morning "Mommy, there is a big, Big, BIG snake with four legs in the back of the house......... and this is what I found....

I am not a specialist in this area but I have been told this is a MONITOR DRAGON...

whatever it is, is moves very fast and is very BIG. He ended up getting on the top of our fence, teetering and then falling on the other side - in the jungle - and we just saw the trees & grass moving as he darted away..... never to be seen again, we hope.
