Zoo clean up

I enjoy going to the zoo and look at what they do there animals? they love when you come to the mines, because then they will immediately become clean and they are free to walk in his aviary. During the day they gathered a bunch of garbage and they can not wait to have you come to them, which would be removed. Do this as quickly as possible, because before the opening of the zoo is only a few minutes. Enjoy your game and good luck.
