|---|---|---|
|
The Banana will spin you out if you even dare to hit one! You can defend yourself with this item. | 1st-5th |
|
New to Koopa Kart Advance, the Triple Banana creates a line of three Bananas that protects you from up to three items. | 1st-3rd |

|
The Triple Red Shell deploys a line of three Green Shells behind your kart that can be used defensively or offensively. | 4th-8th |

|
The dreaded Blue Spiny Shell targets the racer in 1st place and runs into it, tossing it upwards with an explosion. This game gives it wings, meaning it flies over other racers on its way to 1st place. This item can be avoided if you skillfully perform a drift. | 4th-8th |
|
The classic Mushroom gives you a speed boost that allows you to ignore off-road terrain that would normally slow you down. use this to make shortcuts. | 2nd-8th |

|
The Lightning item will zap everyone except you, slowing them down and making them drop their items. If you're in last place, you will grow back almost instantly. However, if you're in first place, you will be small for a long time. | 9th-12th |
Special Items[]

Chain Chomp (New Item) |
The newly introduced Chain Chomp attaches himself to the front of your kart, allowing you to autopilot the track and bowl over any players within your path.

Trivia[]
- This is the last Koopa Kart game to feature just new tracks, as starting from the next Koopa Kart game, there will be retro tracks alongside the new tracks. It is also the last Koopa Kart game where Hammer Bro and Dry Bones are heavyweights and Monty Mole, Shy Guy, Spiny, and Buzzy Beetle are middleweights. The first one will become a middleweight, while the remaining five will become lightweights.
- Starting from this game, Lakitu is a middleweight.
- This and Super Koopa Kart are the only Koopa Kart games without any unlockable characters. Similarly, this is the only Koopa Kart game to feature more characters than it does courses; there are twenty-four characters in this game and only sixteen courses in this game.
