2008 Thanksgiving event

acording to jagex a turkey should be released sometime this month this is what jagex has to say.

Finally, after that huge update will come something much, much smaller! For a few days over the last weekend of November, you’ll notice Thanksgiving turkeys wandering around the map, gobbling and generally minding their own business. Hunt them down for some tasty drumsticks or find the turkeys in disguise for a special reward. Look out for more short celebration updates like this in the future.
