Water Geyser

Water Geysers, or simply Geysers, are pillars of water that either appear as obstacles or rise up from bodies of water and can be used as temporary platforms.

Mario Kart: Double Dash!!
Water Geysers first appear in Mario Kart: Double Dash!! as course hazards. They are found in Dino Dino Jungle inside the cave and before the finish line, where they erupt out of raised cracks in the ground at regular intervals. If a racer drives into one, they are knocked into the air and drop any items they are holding.

Mario Kart 7
Water Geysers reappear alongside GCN Dino Dino Jungle in Mario Kart 7, where they flip racers over if they come into contact with them. Racers can also perform a trick off the geyser spouts.

Mario Kart Tour
Water Geysers appear once again in Mario Kart Tour in GCN Dino Dino Jungle, 3DS Wario Shipyard T, RMX Vanilla Lake 1, and Paris Promenade 3's Do Jump Boosts challenge. Unlike their previous appearances, if the player drives into them, they are launched into the air and given a Jump Boost without spinning out or flipping over. Water Geysers underneath manhole covers also appear in New York Minute, New York Minute 2, New York Minute 3, and New York Minute 4. They also appear in Bangkok Rush T, sprouting out of the. Like in Mario Kart 7, the cracks where the Water Geysers come out of can be used to perform a Jump Boost, while a Jump Boost on the Water Geysers in the New York Minute courses can only be performed when the manhole covers are shaking.

Mario Kart: Live Home Circuit
Water Geysers return in version 1.1.0 of Mario Kart Live: Home Circuit in the Geysers environment, this time simply splashing the screen with water and making the player deviate from its trajectory.

New Super Mario Bros. U
Water Geysers make their first appearance in a Mario platformer in New Super Mario Bros. U, where they rise out of bottomless pits and other bodies of water. This time, rather than serving as obstacles, they help players across gaps and reach high places. If Mario jumps into one, he will be able to swim until the geyser pushes him to the top by its force. If Yoshi gets hit by an enemy and runs into a rising Water Geyser, he will stop when he reaches the top. They appear in Above the Cheep Cheep Seas, Urchin Shoals, Waterspout Beach, during the battle with Larry Koopa, and World Coin-7. They are also an integral part in navigating Sparkling Waters. They behave similarly to Sand Geysers, which also appear in the game as well as in New Super Mario Bros. Wii.

Super Smash Bros. series
Water Geysers reappear on the Mushroom Kingdom U stage in Super Smash Bros. for Wii U and Super Smash Bros. Ultimate, showing up at any point during a match. A Big Urchin can occasionally be seen floating on one of them as a stage hazard.

Other appearances
Fountains of water similar to Water Geysers appear in Super Princess Peach, where its spouting height can be decreased by the cyclone created by the Joy vibe. Also, geysers from the level Gushin' Geysers in Donkey Kong Country Returns 3D are also similar to Water Geysers as they can propel Donkey Kong and Diddy Kong upwards.
