He is in New Jersey, near an old abandoned house.
You cannot 'win' the Jersey Devil. If you want to find her/him, go to the Himalayas to get a lantern from a munk, then go to the Loch Ness place, and get the matches from the pub. Go to New Jersey, and ride the motercycle into the forest. (You also have to have metal cutters for the dumpster)
The monk from the Himalayan temple gives it to you.
Once you enter the abandoned house in the woods, there will be a noise in the attic. When you enter the attic, all that is there is a raccoon. Go back downstairs. The New Jersey Devil will be looking at you from a window when you get down there.
In New Jersey from cripids island IN THE DUMP

On Cryptids, you go to the Himalayas and ask for the Yeti skull. He will not give you it, but you will be handed a lantern to 'light your way' as he claims.
In New Jersey's gas station bathroom but only part of it.
You follow the instructions on the bathroom door (hey, this is Poptropica we're talking about. Are you still even surprised at this sort of thing?)
