Not the most innovative of titles but still a game that requires a lot of skill. Your objective is to collect bananas. (Oh well it takes all sorts.) You play the role of the big monkey brother, and you throw your younger monkey brother upwards, where other monkeys are waiting to catch him. There are bananas on the way to collect, and collecting them gives you points. This might sound confusing, but a look at the screenshot should help you understand.

You can decide the angle of the throw using the joystick -- and the rest depends on your timing. The monkeys swinging on top may move very fast or slow, so you have to time it just right. There are two modes: Arcade and Time Trial both self-explanatory. (Arcade is easier -- you can take your time to decide the throw; in time trial, the time is limited, so you have to hurry.)

There are up to 10 lives per game, and depending on the number of bananas you collect and the height you attain, you receive points. This game is the most difficult of these four.
