Water Valve

Water Valves are blue variations of Warp Pipes that appear in Mario vs. Donkey Kong 2: March of the Minis. They are encountered in only two levels in the game, Room 3-2 and Room 6-2, where they appear alongside standard Warp Pipes.

They appear with red colored handles and a yellow flashing arrow. If the player swipes their handle downwards, Water Valves will cause the water level in certain areas to either rise or fall, allowing the Minis to cross over bodies of water using rafts to reach otherwise inaccessible ledges. However, depending on the current water levels and the Water Valve used, a Water Valve may not change the water level.

Room 3-2 features two Water Valves, one horizontally oriented and the other vertically oriented, alongside two bodies of water. Both the left and right bodies of water in the level start off with a low water level. The player cannot use the horizontal Water Valve at first; however, if the player uses the vertical Water Valve, it will dispense water, raising the water level of the body of water on the right. The player can then use the horizontal Water Valve to drain the body of water on the right and raise the body of water on the left. The player can then use the vertical Water Valve to raise the right body of water again without changing the left body of water; afterwards, both bodies of water will have a high water level and neither Water Valve can be used.

Room 6-2 features three Water Valves, two horizontally oriented and one vertically oriented, again alongside two bodies of water. The layout and function of the two rightmost Water Valves are similar to how they appear in Room 3-2; however, the leftmost Water Valve appears on the left side of the left body of water, allowing the water in the left body of water to be drained. Thus, the water levels in Room 6-2 can be changed at will.

Due to their complexity and difficulty to implement in custom levels, Water Valves do not appear in the Pipe Works or Toadstool Castle construction kits, and cannot be used in the Construction Zone.
