So what do Bratz Ponyz
do all day that would warrant creating a game? I'll lay your curiosity to rest: Ponyz brush their hair and put on mascara continually, almost without rest.
Bratz Ponyz is basically a set of mini-games. You will be given a set of 4 mini-games to complete, and then you are required to find a meteorite, then the cycle repeats. Why do you have to find a meteorite? Because there's something pretty inside, that's why. Yes, this is the reason you're given. But after you've applied hair glitter and tattoos to a pony, who's the crazy one, eh? Oh, and I'll spoil it for you, there's furniture inside the meteorite. That's probably why your pony can never touch any of it: for fear of space-furniture radiation poisoning. Really, your Ponyz can't sit on or interact with all this furniture that you play the game for. All you can do is look at the furniture and then go play more mini-games.
But really, any additional amount of interactivity with the environment would have been nice. After a few iterations of the mini-game cycle, you are required to search for items in order to unlock the new mini-games. That means you have to search all over the map for a hidden item. Gradually, you have to search further and further for the items. You can find a few hidden mini-games and pictures for your house while you're out there searching, but not much else. Sometimes you'll meet another pony who will give you a clue, but usually they repeat something they've said a hundred times before. There's just not much to do but walk and walk until you find the feather or bead or other item that you need.
What's more, the mini-games soon start to repeat. So in one cycle of mini-games, you may be washing your Ponyz face and putting on mascara. In the next cycle, you may be putting on mascara and then eye shadow. You soon start to realize there aren't any new mini-games coming, and that they are just going to keep repeating in a different order.
And finally, story is almost non-existent in Bratz Ponyz. Your job is to become the best citizen of Ponyz Island, that's all. Past that, you're not told anything more about why you're endlessly repeating these games or why you're salvaging furniture from meteorites. Needless to say, it gets dull very soon.
