I happened to notice they took out the Boo item in Mario kart Wii. It was the only item that turned you invisible and would let you steal one of your opponents items away. This item was in the first Mario kart for the SNES all the way up to the Nintendo DS. Then Suddenly they must have replaced Boo with the Lighting Cloud item for the Wii which I hate. Any ideas what made them finally take out this item that's been in the Mario Kart history for so long?

Boo isn't in Mario Kart Wii.

However, King Boo is unlockable in the game by winning a gold trophy in the 50cc Star Cup.
