Jetfish

Jetfish are aquatic creatures found almost exclusively in the Shoreline.

Appearance
Jetfish have medium-sized black bodies, with two purple eyes and two sets of side and tail fins. Their eyes resemble rings in water, but constrict on land, taking on a more circular shape. Additionally, the fronts of their bodies may sometimes have a few sets of whiskers.

Abilities & behavior
Jetfish can eject a high-pressure stream of liquid from an opening between their tail fins. This makes them excellent swimmers, capable of swiftly moving through large pools of water with ease. They remain surprisingly mobile even on land, where they move by performing quick spontaneous jumps.

Food
Jetfish may grab onto and eat Blue Fruit,  Bubble Fruit,  Batflies and   Leeches. Despite never appearing in the same regions naturally, Jetfish can also eat Squidcadas.

Harassing
Jetfish attempt to harass the player at low and default reputation. On their own, they do this by ramming into the Slugcat, which will often temporarily stun, knocking any items or creatures (including other Jetfish) out of its hands. This behavior is much more dangerous in packs, and a group can easily drown the Slugcat by constantly stunning and blocking it off from the surface.

Utility
When grabbed, Jetfish provide a substantial boost to the player's underwater mobility. They're fairly responsive and don't make many movements on their own, allowing the Slugcat to get through long flooded tunnels without drowning. They're also quicker than Leviathans, which makes traversing the long stretches of water found in the Shoreline much safer. The jet of liquid they release grants a good amount of momentum mid-air, which can often come in handy for getting up to poles or high ledges. As a drawback, Jetfish are very cumbersome on land, and too heavy to carry up poles by weaker Slugcats like the Monk & Survivor.

Variants & attributes
Jetfish's side fins can take on a variety of shapes. Their tail fins vary in length, thickness and shape. The same is true for the 0-3 sets of whiskers found at the fronts of their bodies, which can also protrude in different directions.

Trivia

 * Jetfish are immune to Leeches.
 * A dead Jetfish will retain the eye shape it had before death, both in water and on land.
 * Jetfish do a small amount of damage at high speeds, meaning that they may accidentally kill each other when harassing the Slugcat.
 * Two albino Jetfish can be found in the Subterranean as the Hunter.
 * The Hunter is strong enough to perform a slidejump while holding a Jetfish. Doing so will cause them to travel approximately two and a half times farther compared to a normal slidejump. This property can be used to easily obtain the [[File:Jellyfish icon.png]] Jellyfish Arena unlock.
 * Bubble Fruit and Blue Fruit reflect thrown [[File:Spear icon.png]] Spears. They don't lose this quality when grabbed by a Jetfish, turning it into a makeshift shield.
