Water Geyser

Water Geysers, or simply Geysers, are pillars of water that 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. Water Geysers reappear alongside the course 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.

Water Geysers later appear in New Super Mario Bros. U, where the 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. 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.

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.

Fountains of water similar to Water Geysers appear in Super Princess Peach, where its spouting height can be decreased by using 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.

Trivia

 * If Yoshi gets hit by an enemy and runs into a rising Water Geyser, he will stop when he reaches the top.
