Downtown
Description
The Underground City (which can also be called the Underwater city depending on the tide) is a secret area on the game Super Mario 64 and the level in the game, Wet Dry World. To get there, the player has to launch Mario into a very tall fence at high tide (it is inaccessible at maximum or any other tide). Once within the cage, you must swim through a tunnel with partially closed gates as fast as you can before Mario loses all of his air reserve (his health). The city has 8 Red Coins hidden all around and a Power Star within a fence. To get the star, you have to get the Invisible Cap (or Power Flower for Luigi in the DS remake) and become invisible, then run through the fence. To retrieve all of the red coins you have to look around by jumping on top of the buildings, balancing on thin walls and breaking Bricks. There are some enemies here as well, but they are fairly easy to avoid.
