Jetfish

Jetfish are medium-sized, neutral, squid-like creatures with purple eyes found in Shoreline and Subterranean. They travel quickly through water using their two tentacles and can store water inside themselves to use as propulsion when breaching. Although they seem to playfully harass the Slugcat, in larger groups they may attempt to aggressively drown it. Albino Jetfish can be found in the body of water on the eastern side of the Subterranean region. As with grappling worms and squidcadas, a Jetfish can be ridden by grabbing hold of it. While Slugcat is stationary, mounted Jetfish have a tendency to influence player movement, struggling against the player's grasp similarly to a Squidcada. When directed, the Jetfish enables speed and maneuverability in water that is much faster than the Slugcat's base swimming speed, allowing the player to get through certain areas that would be impossible alone. Jetfish can be lured to the Slugcat by certain food items. The food items that lure Jetfish are popped Bubble Fruit and Blue Fruit.

Be careful if you are trying to bring a neuron fly to Big Sister Moon, since Jetfish can dash into Slugcat direction and knock it out of your hands.
