There are many short blocks with some of the primary colors and other weird colors. Although it is based off of Block Fort from Mario Kart 64, players cannot go up ramps to the top of a block and cannot go on a bridge connecting one block to another. However, there is a gray and tan colored block that can be entered because there is a pathway cut through it. There is a hood over this block, sort of like saying it's a hiding spot. There is also a blocked part in one of the corners so that no one can get over to the next turn because the pathway on the next turn is higher than the pathway beside it. There is also a Mario Kart Wii battle stage called Block Plaza, which is based off of Block City.
