Chirpy Chips

"These guys are the Chirpy Chips. With their sea anemone lead singer and a sparkling electronic sound, this unique four-piece has been setting the Inkopolis Top 40 on fire! Take a listen to their latest single, Shellfie, which is also the background music you'll be hearing during battles now!"

The Chirpy Chips are a four-person chiptune-style band. Two of their songs were added in version of, with two more were released as part of version  of , and two more with the release of the Chill Season 2023 of. They briefly disbanded sometime before the release of their Splatoon 2 songs, but quickly reformed.

Songs
Shellfie and Split & Splat are only heard in battles in, Blitz It! and Wave Prism are only heard in battles in , and Slopping Spree and No Quarters are only heard in battles in. Shellfie and Split & Splat also appear in Splatoon 2 as Squid Beatz 2 tracks unlocked with amiibo. The original four songs appear as background music in the Battle Lobby in Splatoon 3 and are playable through the jukebox.

Harmony
Harmony is the band's vocalist and synth player, a relaxed sea anemone who goes her own way. Since her voice is altered in the band's music, she usually lip-syncs during live performances. She is in charge of the band's visuals. She exhibits peculiar movements when singing and talks in a loose manner between songs, which is popular with fans. However, due to her lack of motivation, she is often late for practice. Similarly to Annie, she has a bright color scheme and a small clownfish in her hair, which is dying due to neglect. In the band's second album cover, she is shown making music using various Nintendo consoles.

In Splatoon 3, she appears as the shopkeeper in Hotlantis, running the store in the manager's absence.

Clash
Clash is the band's guitarist and backup vocalist, an uncontrollable, brightly-colored Inkling. He has bright purple tentacles styled into large spikes and what appears to be four fangs instead of the typical three. He has a sunny disposition and epitomizes the band's energy. He was formerly a member of a punk band called BariBari and formed the Chirpy Chips with Orion later on. He likes big vending machines and has an irresistible urge to run on any downhill slopes he sees, causing him to run off a lot. Like Harmony, he lipsynchs during performances.

Orion
Orion is the band's bassist, a shy flapjack octopus who does things at their own pace. On the band's first two album covers, they wear a shirt referencing the album art of Pink Floyd's The Dark Side of the Moon, but with a squid-shaped prism. They are the band's composer, though they also compose their own music and quietly post it online. They like to make sure the band keeps a chiptune sound, but they dislike performing and standing out in public. They are an intellectual and geeky type who likes things that are strange and outdated.

Sid
Sid is the band's drummer, a crab who quietly watches over the others. They are the band's oldest member and have played for a number of other bands in the past, gaining a strong reputation for their musical techniques. They rarely ever take the lead, rather focusing on supporting the others. They are usually easygoing but are known to quietly snap once a year. Their shirt design has what could be the Inkling version of.
