Special Items: (Partnership items listed below.)
Mario and Luigi: Mario and Luigi have red and green fireballs that both have different effects. The red fireballs bounce in a zig-zag direction and the green follow in a straight line until they collide with another driver.
Peach and Daisy: Peach and Daisy both have protective hearts to absorb items. Let's say a red shell is fired at Daisy and she has the protective heart equipped. This means the red shell is absorbed and now it's in Daisy's inventory!
Yoshi and Birdo: Yoshi and Birdo have a green egg and pink egg special. When they are thrown at another competitor or at the track, three normal (or on a rare occassion, special items) are layed upon the track.
DK and Diddy: These naughty apes both carry a giant banana peel in their inventory. It acts as a normal banana peel, but it's much larger in size.
Bowser and Bowser Jr.: The koopa duo carry the giant spiked shell, which takes over almost the size of the track in space itself! It can be fired forward or backward and it causes mass destruction.
Wario and Waluigi: Wario and Waluigi behold the Bob-Omb. It can be thrown at another driver or layed upon the track. Make sure to not get caught in it's detonation!
Baby Mario and Baby Luigi: The babies can unleash the Chain Chomp. This acts kind of like the Starman in it's own way. It pulls you forward at a faster speed and can demolish other drivers that get in harm's way. It's however hard to handle!
Troopa and Paratroopa: The two yellow turtles can equip three green or red regular shells. These are the only two characters who can use three green or red shells.
