Where do Monsters live?

This is the question I was asked this morning by Joshua.  At first I wasn't sure how to answer it but I said Monsters don't live anywhere because they are not real.  So Joshua said, "I don't mean in the Philippines.  I mean in the jungle". (Note: the Philippines can mean Brookside - our subdivision - or Manila. They are not quite sure of the whole country concept yet!)  I wasn't sure whether to laugh at this point but decided it would not be helpful.  So I said again, that they weren't real and therefore did not live anywhere. Joshua spent quite some time trying to convince me otherwise but I think I won!
