Blue Bus

A Blue Bus is an obstacle that is seen in Mario Kart DS on two courses: in Shroom Ridge of the Flower Cup, and in Mushroom Bridge of the Leaf Cup. It is found driving on the main road. Those who hit the bus will spin out briefly. The Blue Bus features red, orange, and yellow zig-zag stripes on its sides.

Trivia

 * The Blue Bus is similar to a cross between the Red Bus and the Star Travel Bus of Mario Kart: Double Dash!!.
