Wet-Dry World



Wet-Dry World is the eleventh course in Super Mario 64 (and its remake Super Mario 64 DS) filled with water. The water level of the level is controlled by the Seven Crystal Taps. The initial water level is altered at what altitude Mario Jumps into the painting to enter the level. Under Wet-Dry World is a "downtown" area. In Super Mario 64 the Underground City holds a Metal Cap, a Vanish Cap, and the eight Red Coins, while in Super Mario 64 DS the caps are replaced with Power Flowers.

The painting is in the second story of Peach's Castle and has a Skeeter on it. Various enemies inside include Amps, Skeeters, and Heave Hos.

Downtown
To get to the abandoned downtown, the player has to launch Mario into a very tall mesh cage when the level is at maximum high tide. It is inaccessible at any other tide level. Once within the cage, the player must quickly swim through a tunnel with partially closed gates before Mario loses all of his air reserve.

The town has one Power Star and obtaining eight Red Coins can also unearth another Star. To get the Power Star, the player must obtain the Invisible Cap (or Power Flower for Luigi in the DS remake) and become invisible, then run through a cage which contains the Star. To retrieve all of the Red Coins, the player must look around by jumping on top of the buildings, balancing on thin walls, and breaking Bricks, all while strategically utilizing the Crystal Tap and the ! Switch.

There are some enemies in Downtown as well, such as Skeeters and two Fire Spitters. The latter was removed in the DS remake because they were completely useless in the small amount of water found in Downtown. Other Items found here include green and blue ! Blocks. In the DS remake of the game, a lone Pink Bob-omb can be found, who reveals where the eight Red Coins are located.

Downtown is a somewhat modern yet small town, having only five buildings (which Mario cannot get into), plant life, and even a "central park" with thin stone walls and a statue of a pyramid. Another landmark is the small "shrine" that stands in front of the park. It has an opening where the player can collect the Star after gathering all 8 Red Coins. It is unknown what the closed-off caged area was meant to be, if anything.

Shocking Arrow Lifts!
In this level the player must raise (or lower) the water level to a point where they can make their way across several mini elevators, like the one in the Red Coin area in Hazy Maze Cave. They lead to a Yellow Box which contains the Power Star.

Trivia

 * This world was used in a Got Milk? commercial in the late 1990s, featuring Mario, who is unable to jump onto a platform in the first area, so he breaks through the screen, drinks some milk, becomes super-sized and starts walking on the top of the level. Link
