Its not a fake its just different. Its probly just some one trying to make a pet that people can have. I didnt see any think on that packet that said Tamagotchi so it cant be a Tamagotchi its just a different pet that other people no about not us.
It might not be a fake, it might just be a company that wants to make themselves more popular by taking the name "tamagotchi" and using it for their own product.
