Missle Launch:A missle that is fast and allows you to control it until it hits someone or something.Once hit,you will be where you stopped.

Fire Rocket:Same thing as Missle Launch but covers you in powerful flames.

Giga Cannon:Launchs a powerful beam that goes on forever until it hits a wall or object.

Super Cannon:Same as Giga Cannon but can fire 3 times.

I remember the first time this thread was ever made here.

Let's see the ones I came up with were

FLUDD spurt-sends a spray of water on the track making racers slip

Ice Block-makes a large opposing block of ice that breaks when someone hits it

Giga Bowser shell- Just like the bowser shell. But it red with gold spike. It faster and it last the whole race. And you can hold three.

How about a rocket-launcher equipped with laser-sight and designation built with custom grenade launcher?

Oh, and; go Bulls! Though the Clippers can own them any day.

supermushroom

the car become's gigant size and able to squash all other players

Lightning Shell:
Homes in on the player in front of you and makes them small if they get hit.

Rainbow Shell:
Multiple shells go at supersonic speed to all the players in front of you.

Shy-Guy:
Drop it on the ground. It will go left and right until it hits a player. Then it vanishes.

Bowser Bomb (Special used by Giga Bowser):
Throw it and it will blow up part of the course creating a hole that you can fall into. It will be there until someone falls into the hole.

F. L. U. D. D. (Special that would've been for Mario):
Squirt up to 5 water bombs on the ground. They will make wet spots on the course that will make players' steering out of control for 3 seconds (Left is Right, Right is Left)!

Those are MY items!

triple: it makes three of your next item three chain chomps awesome

or a super chomp that carries you through the entire level

Blue Shell Ultra-Does the same thing but also hits all the other players too.

Three-Fold Chance-

Your next Item's effect will be tripled.

Bullet Bill-kart becomes bullet bill and acts like the chain chomp item

Dice Block: The number determines which place you are in.
Poison Mushroom: Opponent controls become more difficult
Wiggler:Creates honey to stop falling off cliffs or edges
Switch hook: Switches spots with opponents

Tnt banana

Car bomb:
Makes a bomb car that drives a round until some1 hits it

Super fireballs:
HOld the y or x button when u have fireballs to charge them up and then when u throw the they will be bigger

Pikmin:
Olimar and Louies special (characters i thought would be cool) they run to the car in front of you and jump on the wheels till they stop.

Grass seeds:
plant grass on an area of the track an slows people down. But can hurt u to. Last a few seconds( around a minute)

Detonating shells:
The koopa team gets detonating red or green shells instead of 3. and triple shell becomes a basic weapon.

Piranna plant:
Plants a pirrana plant on the race track, kind of like a banana but better cuz it makes the back person hang on to the kart.

pikmen bomb: lies on ground like the fake item until someone gets close then it explodes sending pikmen everywhere and slowing the people who get hit by the pikmen

suicidal Yoshi bomb: its Yoshi strapped to a bomb running like a mad crazy dinosaur, then it explodes
