Not bratz, TY Girlz. It's pretty stupid, But GANZ also ripped two small ideas already created. They took TY's animal idea, and perhaps teh internet part rips UB Funkeys and Tamagotchi and Neopets....
But Shining stars is only bears, right?
And ty girlz is humans....
And has webkinz ever had bears in blue, green and yellow? No. And they have never had humans for pets. So practically, ty girlz is for those who want to "hang out" with a online person.
And shining stars is probably for kids who don't want to spend as much money, and like bears in different colors...
But as for the main purpose, it is pretty stupid to copy.
