Gushen

Gushens are purple -like creatures encased in balls of water found in the Seaside Kingdom, Sand Kingdom and Mushroom Kingdom of Super Mario Odyssey. They are normally found floating on the surface of the water in their water balls, occasionally making large vertical leaps. However, when Mario approaches, they shoot a powerful stream of water from their undersides. If Mario captures one, he can use it to fly. The result is similar to F.L.U.D.D.'s Hover Nozzle, in that it propels Mario upwards for a limited time before needing to be refilled by touching water, a Power Moon or a Checkpoint Flag, although the height he can travel to is more akin to the Rocket Nozzle, and the high speeds he travels on water make it akin to the Turbo Nozzle. He is also capable of spinning while shooting to the side to spray all around him, and the water can clean away lava as though it were graffiti, like the Squirt Nozzle. Mollusque-Lanceur, the boss of the Seaside Kingdom, resembles a Gushen in that he is a purple octopus, but it is unknown if there is any actual relation. Gushens turn dark-grey and move slowly on land without their water balls.

Trivia

 * The part of the body that Gushens shoot water from would be the mouth on a real octopus; however, Gushens appear to have tan mustaches on their fronts.
 * Real cephalopods indeed shoot water from their bodies to move; however, these are from funnels higher up on the body, not the mouths.
