Yeah, PETA is wack. I've mentioned this before, but I remember when they had a crazy anti-Nintendo campaign going several years ago. They had a Pokémon game where you play as the Pokémon and fight Ash, who is evil and oppressive. They had a Mario game where you play as a skinned tanooki (raccoon dog) and chase down Mario, who is wearing your fur, still dripping with your blood. The Cooking Mama game is too ridiculous for words.
I dunno what their deal was, but it was pretty demented, unintentionally funny stuff. Actually, those games might still be up today.
