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 is a whole slew of Item Boxes.

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 Double Dash that is not symmetrical in any direction.
 * Block City was originally going to reappear as a retro battle stage for Mario Kart DS, but was removed due to Pipe Plaza being put there instead.
