Zoo Hidden Objects is a game where you have to find all the objects that are hidden within that level before the time runs out. Each new level has a different picture from a zoo and there are ten hidden objects find them all to advance to the next. If your getting stuck on a level why not use the Hint button, but beware for using the hint button takes a small amount of time of the timer. So you'd better be quick.
Click on the objects and try to find all as fast as possible.
