PETA Cooking Mama Flash Game [blood, gore]
PETA has a knockoff Cooking Mama flash game, Mama Kills Animals, with cutesy blood and guts and gore taking all the fun out of Thanksgiving. Plucking a bird, pulling out the internal organs, sawing the head off of a turkey, Cooking Mama is an angry little lady. After every few minigames, you're shown depressing factoids and offered to watch a video of the gory reality of an industrial turkey farm.
The fun part about this game is that you can't actually lose — it just keeps shuffling you into the next levels. After all the gory levels, the game then turns all vegetarian, where you get do things like mash tofu and "shape the tofu turkey." At the end, it urges you to "Take the Pledge to be Veg!"
