Harmony (Splatoon)
Harmony, known in Japan as Paruko (パル子) is the vocalist of Chirpy Chips, a chiptune band popular among squids with their music being played in Splatoon and Splatoon 2. She is also charge of the visuals for them too.
In Splatoon 3 she is the manager of the general shop Hotlantis but also states "I don't really work here, but you can shop around, and I'll sell you stuff.", this is due to the real manager's frequent absence. She sells decorations and stickers there but when she isn't busy she plays with a Ultra Hand. Besides the Ultra Hand being a real Nintendo toy, it could also be a reference how Chirpy Chips uses "old school" gaming music tools such as the game boy for chiptune.

She is a sea anemone with a light skin tone and skinny build. The yellow and black striped hat on her head is that of a hazard symbol with a green and red brim. Her hair has a pink and green gradient with the colors separated by multi-colored hair bracelets with green being at the ends of her hair. She also has a slobbering mouth that is always open with drool hanging out of it. As well as the pink of her hair and drool, her eyelashes are pink with green iris and pink pupils. There is a black and white striped clownfish in her head, but it is dying due to neglect as stated in Inkopolis Illustrated (ハイカラウォーカー, Haikara Uōkā, lit. HaikaraWalker).

Her black T-shirt has a neon green and pink patterns. The skirt she wears is a light green with black shorts under that.
As well as having bracelets tied to her hair, she wear thinner multi-colored bracelets on her left arm.
Lastly she has blue boots with yellow straps and soles and red insides.
While harmony is a musical term relating to her music work, it can also sound a lot like anemone, her species. Other languages also pick names sounding like anemone or harmony in their language such as Monia (French, Italian), Mona (Dutch) and Armonia (Spanish). Her Russian name, Actavia (Актавия, Aktaviya) is a little different coming from anemone (актиния, aktiniya) and octave (октава, oktava)
Her name in Japanese, Paruko, most likely comes from parurando (パルランド), meaning singing in a speaking style. The ko (子) in her name is a common feminine suffix.
