Water Geyser

Water Spouts are pillars of water that rise out of bottomless pits or out of other bodies of water, appearing in New Super Mario Bros. U. They help players across gaps and reach high places. If Mario jumps into one, he'll 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 and Waterspout Beach, and are an integral part in navigating Sparkling Waters.

Trivia

 * If Yoshi runs into the middle of a rising Water Spout, he'll stop when he reaches the top.
