The reason why the tweevils look ugly is because that's the point. They parody Barbie so they're not supposed to fit the bratz aesthetic. Plus they look VERY accurate to the show, I'm surprised they were able to translate them in doll form.
Here is Kirstee and Kaycee fighting over the Kaycee doll, trying to massage the doll's broken nose! Wanted to make a meme/edit of the Tweevils fighting over the Kaycee doll from the new Bratz Tweevils Special Edition 2-Pack! In the original video, they are fighting over a "Boobie" doll.
Here is the Amazon link for the new Tweevils 2-Pack!:
(Español): Kirstee y Kaycee se pelean por la muñeca Kaycee e intentan masajearle la nariz rota. Quería hacer un meme/edición de las Gemalas/Gememalas peleándose por la muñeca Kaycee del nuevo pack de 2 Bratz Tweevils Edición Especial. En el vídeo original, se pelean por una muñeca llamada "Boobie", una parodia de Barbie.
