What's the name of the horse game for the Nintendo DS?

I've been looking for a horse game for the Nintendo DS for a while now. Unfortunately I forgot the name. All I know about the game is that you have to perform different tasks. For this you usually have to ride out and take pictures of certain animals. Now and then you have a few gems under the hoof of his horse.

I wanted to give my niece a birthday present, but unfortunately I do not remember the name.

I ask for quick help.

Good day you look at Amazon because they will find it

There's a game called Horseland, I do not know if that's it

The game is called Pony Friends.

I think so.
