The first is Monkey Target, where you launch a monkey into the air and guide it back down to a safe landing–all the while trying to grab as many bananas and possible. The other mini-game is called Monkey Golf. As the name implies, instead of a golf ball you’ll be sending monkey’s flying through a full 18-hole golf course.
The update is free.
If these new updates entice you at all, the game is available for download through Apple’s App Store for $5.99.
