Bonus level
Select any difficulty setting and complete all normal levels. A bonus level will start during the credits. Get as many bananas as you can while avoiding the falling letters from the credits.

The names of the programmers who made the game will appear above the bananas. All the letters will fall down and you have to try and dodge them.

Extra levels can be unlocked on all difficulties by not falling once. However, once you get to the extra levels, you can die as many times as you have continues.

Extra points
There are a few warps in the game that can result in more points in the normal levels. In the second level in beginners mode, there is a ramp on the opposite side of the original goal. Climb that ramp slowly and you will fall on a floor beneath it, with the goal that transports you to the fifth floor.

Play all mini-games with 2,500 PP
Gain 2,500 PP (play points) then save the game. Put a memory card in slot B. Transfer the saved file to slot B. Open slot B and you can play all mini-games.

Finding bananas
Note where your monkey's head is turning to find the closest banana, whether it can be picked up or not.

Easy points
An easy way to get a decent amount of points is to land on the buoys. They are worth 500 points and an easy 500 if you just get a Magnet Ball. I got over 4,000 points by doing this.

Earning points
The only way I know you can earn points in the game is by doing the main game with 1 player. You will not get any points for more then 1 player so if you wanted to do more then 1 player take it in turns of doing a stage. Under main game each difficulty will earn more points.
Some tips are
If possible get all banana's on the stage.
Even one stage will get points.
Try expert and do as much as possible even a few stages can earn a lot.
Retiring or exiting gets points.
Warping doesn't get less you still get roughly the same score after warping as you would by doing the stages you skipped.

And most of all dont stress out this game requires a lot patience and skill and can take a lot of lives and continues just to complete a stage if you cant pass a stage quite and you should be able to practice it on practice mode if not just keep trying or turn it off and go have a break and maybe calm down and relax and then go back and try to complete the stage.

Monkey target tricks
After selecting a character to play as on monkey target mode you get an option screen which consists of a number and 2 options
1st option lets you choose how many rounds you play you can choose 5 , 10 or 15
2nd option lets you turns off the info at the top of the screen that says stuff like 2x and stuff
And the 3rd option lets you turn off the disc that spins at the start of your turn that decides playing conditions eg clouds , bombs e.t.c.

During the game to make landing easier to land on high point targets eg 100 points e.t.c before you reach the target hold the analog stick down and you will loose speed and altitute thus letting you land with out bouncing a lot and lets you close the ball above your destination getting you high scores.
It takes a bit to master but once you get it you should be getting the 200 targets easy

Warp from stage 2 to stage 5
On stage two of beginner turn around as soon as you start and you'll see a ramp go up the ramp as slow as possible and still make it over the edge. If you did it correctly you should see a goal gate that will take you to stage five.

Unlimited continues
At the start of the game for every 2,500 points you can buy a new mini game, but after you have bought all of the mini games (fairly easy to do) for all the next 2,500 points you get an extra continue after you get 5 extra continues you get Unlimited Continues forever.

Get red warp easy
On stage 18 of Advanced difficulty, there is a blue, green and red warp. An easy way to get the red warp is to just go forward a few feet then go off the right edge. You will fall on a lower platform. Just wait there and the red warp will come by in a few seconds

Easy 200 in target mode
On the level with the pyramids on the two sides: fly straight out to the middle platform, then hang a right.. you should be able to glide gently to the pyramid and drop right on the 200 or 300. use the 3x multiplier for more points

Get master mode
Finish the game using Expert mode with no continues

Warps
On main game mode on beginner difficulty when your on stage 2 you will see a ramp, get your monkey over that ramp and you will be on a platform go through the goal and you get warped to the bonus stage which is stage 5
