Mama Kills is an unauthorized flash-based web game that asks the player to cut off a chicken’s head, pluck its feathers and pull out its giblets.

It’s a parody of Taito’s casual DS game Cooking Mamma and was launched by animal rights advocate PETA (People for the Ethical Treatment of Animals). The organisation has condemned Taito’s game for overusing a large number of animals in its cooking minigames.

The animal rights group says that the Cooking Mama games are "so heavy on dishes that are made from dead animals that the only things missing are the blood and gore." The release comes days ahead of the newest Wii version of the series; Cooking Mama: World Kitchen.

PETA, who are trying to persuade people to eat less meat at Christmas and Thanksgiving holidays, splice facts about animal food production between each minigame. The game claims that over 40 million turkeys are killed each year during the holiday season in factory farms.

PETA marketing manager Joel Bartlett says of the game: "We"re having a bit of fun at Mama"s expense, but there"s nothing funny about the suffering endured by turkeys and other animals who are killed for food. With all the delicious vegan alternatives available, there"s no need to make the carcass of a tormented bird the centerpiece of your Thanksgiving table."
