Nautica

A DJ with talents in rhythm remixing to entertain others

Different rhythm patterns = music samples

Good at noticing rhythms or patterns that others may overlook

Energetic, easily distracted, and maybe a bit chaotic

Speedster Fish who can “enter a hyper-focused speed burst state”.

Able to adapt well to unexpected or off-rhythm situations

Eager and impatient, but also dedicated and quick-thinking

Could be a mail courier

Doesn't overexaggerate or overreact

Keeps everything efficient and simple, but might result in them being emotionally quiet and no-nonsense

Could be a sculptor or minimalist composer

Thrives with repetition and routine; doesn’t like change and unexpectedness

Others might find them boring, but admire their planning skills and perseverance

Might get stuck in behavioral loops until snapped out of it (probably has a hard time breaking bad habits)

“Calm, obsessive, rhythmic perfectionist”

Could be a meditation guide or professional planner

Could be a train conductor 

Tenacious; might ignore things like obstacles or curves, preferring to go straight ahead instead of finding a way around. This also might apply metaphorically, where they barrel straight through problems instead of finding a workaround.

Others might admire their determination, but are also wary of how they solve problems.

Predictable; hates surprises

Less than one beat = small problems → midspin = momentum & flow; odd solutions

“Spin small stressors into something active, dynamic, or even beautiful”

Could be an abstract artist or freestyle dancer/swimmer

Often speeds off in excitement, causing loose things around them to comically spin in place for a moment

Unpredictable, chaotic, “full of kinetic energy but rarely in control”

Could be an acrobat or performer

Might be friends with Swift, since they’re both speedy and energetic

Shapes = big things → midspin = momentum & flow; odd solutions

“Big, structured tasks or patterns confuse or frustrate them, so they improvise, simplify, or detour”

Creative nonconformist; likes breaking the loop

Very indecisive; quick to switch between ideas on the spot

Their indecisiveness also makes them prone to panicking

Could be a mechanic; they seem to have made some sort of "UFO" in the Cursed level

Probably obsessed with all sorts of media, but flip-flops between hyperfixations all the time. The only fixation that's stuck is space and what lies beyond their planet. (Perhaps they find exploring the deep ocean very similar.)

Good at simplifying problems and helping others calm down

*Could be a sort of gardener in charge of an underwater fusion between a bee and a butterfly (combining hexagons & butterfly planet)

Maybe they're in charge of a zen garden where other creatures go to destress and relax

A fish that often gets jerked/snapped back to reality, prone to odd cases of Dèjá vu. They live through scenarios in their head, then get confused when they seemingly re-live the exact same scenarios later on

Sometimes their quirk actually pulls them back a few spaces, like physical Dèjá vu rather than mental, forcing them to re-swim the same area more than once

These traits probably cost them their job, and because of this and their stressful quirk, they hang out in Zen's garden to help out and relax

Slightly smaller than average for their species/age, and others often tease them for this

Their size allows them to enter small spaces without problem; might also be able to alter their size to fit in even smaller spaces

They sometimes help Coz with their hyperfixations, as they also enjoy machines and building things
