Jetfish

Jetfish are medium-sized squid-like creatures with purple eyes found primarily in Shoreline. They travel quickly through water using a sort of propulsion, and can breach the water using a small bit of water stored inside their guts. Although they seem to playfully harass the player, in larger groups they may attempt to aggressively drown it. When playing as the Hunter, an albino jetfish can be found in the body of water on the eastern side of the Subterranean region.

Similarly to squidcadas, grabbing a jetfish will help the player move in water at the cost of significant mobility on land. When holding a jetfish in the water, the player can direct the jetfish to swim at a high speed in any direction. Jetfish can be lured to the player by using certain food items, which are Batflies, Blue Fruit, and popped Bubble Fruit.

Tips

 * Jetfish tend to be more aggressive in groups. Lone jetfish will typically not harass the player at all, while groups of two to three will harass the player much more actively.
 * The player should avoid jetfish if they are are trying to bring a Neuron Fly to Looks to the Moon, as jetfish can dash into the player and knock it out of their hands. This can be avoided by storing the Neuron Fly in Slugcat's stomach.

Trivia

 * Neither species of Leech will attack jetfish.
 * A jetfish's eyes will grow larger underwater and shrink while above it -- killing a jetfish in either of these states will cause its corpse to retain the particular eye shape no matter where it is placed.
 * Jetfish can kill other jetfish and will play with their corpses -- this is because jetfish do a small amount of damage when hitting something else at high speeds.
 * Jetfish will actively hunt and kill Batflies, and will also eat dead ones by picking them up and bringing them back to their underwater dens.
 * If the player performs a slidejump while holding a jetfish, they will travel approximately two and a half times farther than a normal slidejump. However, the utility of this is diminished outside of Hunter mode, as the Monk and Survivor are not strong enough to bring Jetfish up poles. However, in Hunter mode, this property can be used to easily obtain the Jellyfish arena unlock.
