Block City

Block City is a battle course in Mario Kart: Double Dash!!. It is rather simplistic, simply being a huge square with four block pillars (one of which includes a narrow shortcut with a double item box) and some edges; it is seemingly based on and named after Block Fort of Mario Kart 64. In each of this stage's corners, there are several Item Boxes.

Block City was going to return in Mario Kart DS, but was removed from the final version of the game.

Trivia

 * Block City may be named after the poem of the same name from Robert Louis Stevenson's A Child's Garden of Verses, which similarly features a city made out of children's playthings.
 * Block City is the only default battle arena in Mario Kart: Double Dash!! that is not symmetrical in any direction.
