The concept of the game is an updated formula of a classic idea. To move the monkey, the player tilts the platform the monkey is sitting on. The ultimate aim is to get the monkey through a goal at the end of a course within a certain period of time. The player obtains a score based on how much time they have left at the end of the level, and how many bananas they collect. The game has a very nice difficulty curve, starting at being easy enough for a five year old, and finally progressing to extremely hard levels. The game makes it very obvious that the bananas used are Dole.
The evil Dr. Bad-Boon has stolen all of the bananas from the island that AiAi, MeeMee, GonGon, and Baby live on. These for monkeys chase Dr. Bad-Boon through 10 different environments, each with 10 levels. Unlike the first game, there are unlimited lives and no restrictions on the order the levels within each environment are played.
This mode is a lot like the original game. The player is given a set number of levels to complete within a set number of lives. Also, some levels have multiple goals that will allow the player to skip levels. There are four difficulty levels-- Beginner, Advanced, Expert, and Master. Beginner has 10 levels, Advanced has 30, and Expert has 50. If all of the levels in a difficulty are completed without losing all lives, there are 10 extra, more difficult, levels to play. If the Expert stages and extra stages are completed, the master difficulty is unlocked. The Master difficulty has 20 extremely hard levels.
Practice mode provides players with a means to play any level they've already defeated before with unlimited lives.
These are extra little games that can be played by up to four people.
Monkey Race 2
Very similar to the original monkey race. In Monkey Race, the player races around the track collecting power-ups and trying to avoid other monkeys' attacks. These power-ups include turning other monkeys into ice cubes or hexagon-like shapes, shooting bombs, laying bananas, boost, and shooting missiles. It is very similar to Mario Kart. Most of the tracks are very easy to fall off of like in the main game. Monkey Race has six different tracks.
Monkey Fight 2
Ever wanted to pit four monkeys against each other in a brawl? In Monkey Fight the player takes control of a monkey with a boxing glove attached to his ball. They swing it at enemies and try to knock them off of the level. There are a few power-ups do be gained here as well. They makes the monkey punch harder, their gloves bigger, their gloves longer, their attack spin. There are three different levels. The only difference between this and the first monkey fight is that the player can charge up the punch.
Monkey Target 2
However fun it might be, this game is not the popular department store filled with monkeys. The player rolls their monkey down a ramp and launch it into the air. Then they deploy their wings and float to a target. To land they just close the wings, and whatever point value the monkey lands on is how much they earn. There are three different courses, some have multiple targets. The player can get some power-ups in here as well. They let the monkey immediately stop when they reach the target, slow down quicker, and multiply the score. They can also collect floating bananas in mid-air to increase points. Monkey Target 2 has easier targets than the original.
Monkey Billiards 2
Monkey Billiards two adds the 15 ball game mode and Japanese 9 ball game mode. It does not have much extra. The game physics and shooting modes are similar to Bankshot Billiards.
Monkey Bowling 2
Monkey Bowling 2 keeps both of the first modes, and adds a third. Normal mode is a standard game of bowling. Challenge mode gives the player 12 throws to knock down all of the pins in 10 different formations. The third mode makes the lane different in each frame. Sometimes it will be moving, sometimes just really curved. In every other game, all of the characters are the same. In bowling, each character has it's own strengths and weaknesses. AiAi is all around. MeeMee has the best curve. GonGon has the fastest bowl. Baby's bowls are the easiest to aim.
Monkey Golf 2
Monkey Golf 2 is mainly a normal 18 hole golf course with some extra crazy thrown in Monkey style.
The rest of the games are locked at the start, and must be bought using play points.
This is like monkey race but it boats. Push the left and right triggers alternatively to make the monkey paddle the boat. There are many different power-ups to pick up, but only one course.
Monkey Shot is a lot like light gun games such as Duck Hunt. the camera fly's around in the air through a few levels. Enemies fly towards the screen and the monkey must shoot them with the cross-hairs. This game is played in first person. There are quite a few power-ups to pick up, including some to make shots bigger, provide a bigger clip, and make the gun fire faster.
As the name implies, monkey dogfight is an air combat game. Each monkey can shoot it's machine gun, which it has infinite ammo for, or missiles, which there are only a few of. The last monkey flying wins. Bananas can be picked up to refill health. There are some power-ups too. There are 3 different levels.
The rules are exactly like regular soccer, try to score more goals than the opponent. Before each match the player picks which monkeys they want on their team, each of them having specific advantages and disadvantages. From there the game is just like regular soccer.
The player controls either the pitcher or the batter. As the batter, they can move around in the batters box and swing at the pitch. The outfield wall has many different compartments in it. Which compartment the ball rolls to is how many bases the batter runs. There are also ramps scattered throughout the field that count as home runs if the batter hits one. When the pitcher throws, he can keep changing the speed or direction of the ball until the batter hits it. He also gets to control the outfield when the batter hits the ball. If someone in the outfield catches the ball before it gets to a compartment it is an out.
Monkey tennis is much like regular tennis with singles or doubles modes.
