Jellyfish

Jellyfish are creatures found in Splatoon. They can be observed walking around Inkopolis, wearing various articles of clothing. They are the second-most common creature in the city, but most do not speak Inkling and cannot be interacted with.

Description
Unlike Inklings, jellyfish look fairly similar to their aquatic counterparts, with the most significant change being that their bodies have taken on a more humanoid shape. They have large, round heads, with their only facial features being a pair of very close-set eyes with square-shaped pupils and no visible irises. They have a pair of upper tentacles that serve as their arms, and a ring of eight lower tentacles that serve as legs. Being quite gelatinous, they noticeably jiggle when they move. Through their translucent skin, squishy innards can be seen. Greenish-blue skin seems to be uniform across the species, with the exception of Jelonzo, whose skin is pure blue with a slight purple tinge in some areas. Though jellyfish have been shown to wear a variety of clothing, most only wear a t-shirt. Many of their shirts are just smaller versions of Inkling shirts, such as the Pirate-Stripe Tee and the Black Squideye. During a Splatfest, all jellyfish in Inkopolis Plaza wear a Splatfest Tee in support of their chosen team. However, their version of the shirt lacks the wristband, as they have no wrist to wear it on.

While most jellyfish have never been heard speaking, Jelonzo's voice has been heard. It is somewhat high, being very close in pitch to Annie's, but louder and clearer. It is possible that other jellyfish have a similar voice.

Jelonzo
Jelonzo is a blue jellyfish that owns Jelly Fresh, a clothing store in Inkopolis.

Appearances
Jellyfish do not appear in Ranked Battles.

Inkopolis
Jellyfish can be seen in and around Inkopolis Plaza, performing various activities.
 * Two jellyfish operate the air traffic control center above Inkopolis Tower.
 * Jellyfish stroll around the plaza, wearing different pieces of clothing.
 * Some jellyfish can be found sitting on benches, both inside and outside the Plaza.
 * Below the Squid Sisters' studio, a jellyfish can sometimes be seen dancing beside a pillar.
 * A jellyfish often stands at the train station behind the Plaza.

Arowana Mall

 * Many Jellyfish can be seen behind the shop windows.

Blackbelly Skatepark

 * Some Jellyfish can be seen outside the skatepark.

Bluefin Depot

 * Across the water, outside the bounds of the Stage, there is a lone jellyfish which can only be seen up close by zooming in with a scoped Charger. It is not always there, but when it is, it either sits peacefully by the edge or stands and stretches its tentacle into the water.
 * On the opposite side, along the wall of Miiverse posts, there are sometimes a few jellyfish standing or sitting around. Some of them seem to be spray painting the wall.

Camp Triggerfish
Jellyfish can be seen across the lake at Camp Jellyfish, at a location known as Camp Jellyfish.
 * A jellyfish can be seen hopping around in a canoe.
 * Other jellyfish tend to stand on the Camp Jellyfish fort.

Flounder Heights
Jellyfish appear to live in Flounder Heights, and can be seen performing daily activities there.
 * Two jellyfish can be seen behind each glass door. One appears to be dancing and cheering on battling Inklings, while the other stands with a tentacle on its "hip."
 * A group of jellyfish play at the nearby playground.
 * There are two balconies on either side of each team's Spawn Point, with a single jellyfish on each one. One of them is usually dancing.
 * During a Splatfest, with the lights in the apartments on, silhouettes of jellyfish can be seen in some of the windows.

Hammerhead Bridge

 * Several Jellyfish can be seen dancing or sitting down on the top railings of the bridge.

Kelp Dome

 * Outside the boundary of the Stage, a few jellyfish, possibly workers for the greenhouse, can be seen.

Moray Towers

 * There are four jellyfish next to the ramp on each side of the stage, standing next to a car inside a parking lot.

Port Mackerel

 * Behind the glass forming the boundary of the Stage, a jellyfish can sometimes be seen directing a forklift.
 * Also behind the glass, a pair of jellyfish can sometimes be seen talking to each other. One is smaller than the other; it may be a younger jellyfish or simply a short one.

Saltspray Rig

 * Jellyfish often stand on the towers surrounding the map, either alone or in pairs. Some of them dance.

Urchin Underpass

 * Some Jellyfish can be seen cheering from behind the secret alley windows.

Walleye Warehouse

 * Outside the stage's boundaries, jellyfish can be seen walking around and spectating the current battle from the warehouse's large windows.

Trivia

 * Most jellyfish in Inkopolis cannot speak the Inkling language. An exception to this is Jelonzo, who is able to speak it, albeit with a thick accent.
 * Jellyfish are also heavily featured in most of the Arcade Games.
 * It can be inferred that Jellyfish have large sums of money as they are often seen in cars, and can afford rent at Flounder Heights, which is known to be expensive. Camp Jellyfish also seems significantly larger than Camp Triggerfish, providing evidence for this theory.
