Wyld Roamer
From out of nowhere, two feathered wings reach around your neck, slowly adding pressure until it is hard for you to breath. One of the locals sees you're in trouble, runs over and grabs something from your back.
"This one got a little over-excited." he says with a grin, "It seems to like you."

You stumbled on one of the 14 hidden Roamers. Try to collect them all, who knows, you might get something if you can tell me where you found all of them ;)
