Bottom Feeders

"A new band called the Bottom Feeders has been tearing up the Inkopolis charts lately. The band is fronted by a tropical-betta-fish violinist, features vocals by a dude made of seaweed, and also includes a shark, a scallop, and a globefish. Their unforgiving yet catchy music style is the product of fusing ancient Celtic sea shanties with punk rock."

- Live from the Squid Research Lab

The Bottom Feeders are a five-person Celtic rock band. Their songs were added in Splatoon 2 ' s Version 2.0.0. They originate from a country up north, and predominantly perform live, spending most of the year on tour. They have been consistently using their own label ever since their debut. In-universe, it is stated that the organization of their performances, as well as the songs' progression, often change depending on the mood of the members.

Songs
In Japanese, each song title has an English part and a Japanese part; for localization, only the English part was kept.

Fin Bottom (フィン・ボトム)
Fin Bottom is the fiddler, a glamorous tropical betta fish and the focus of the band's sound. They want to share the goodness of traditional music's sound no matter how much the world changes. They have a stubborn personality, and often do things in their own way, leading to the band almost dissolving on multiple instances. They do not get along with the members of Ink Theory, which debuted at the same time.

Tangle Bottom (タングル・ボトム)
Tangle Bottom is the vocalist, a man made of the edible seaweed mozuku and the leader of the band. In their album art, he wears a plaid kilt, combat boots, and large square glasses, reflecting the band's fusion of various styles. He is a young man with a rebellious spirit, dissatisfied with how voguish music has become and wishing to return to more straightforwards styles. However, the songs he writes are mediocre, and the other members are quite harsh on him. Up until recently, he was unaware of where his voice was coming from, but it turns out to be produced by the friction of the string-like organs that make up his body rubbing against each other.

Murutā Bottom (ムルター・ボトム)
Murutā Bottom is the guitarist, a Yesso scallop with a weakness for cute girls. Unlike Fin Bottom and Tangle Bottom, they are not as particular about the sound of the band and are fine with anything as long as they are having fun.

Fuka Bottom (フカ・ボトム)
Fuka Bottom is the bassist, a shark that likes motorcycles and meat. Much like Murutā Bottom, they are fine with doing anything as long as they are having a good time.

Blow Bottom (ブロウ・ボトム)
Blow Bottom is the drummer, a globefish who wears a plaid kilt similar to that of Tangle. Like Murutā Bottom and Fuka Bottom, they also don't care much about the band's sound as long as they are having a good time. They are a member of a Rainmaker team with Kuze and Ryū-Chang, and they have an only daughter that they care for and adore.
