Flap is my OC that I made for a concept of Splatoon 4 idols, he's in a 4 idol group and every splatfest has 2 teams that divides the idols into two groups. The members are Berry, a quid, Trouter, a salmonid and Lunulata an octoling. Examples of how the splatfests would work: the topic is Salty VS Sweet or something, Berry and Flap go on team salty and Lunulata and Trouter on team sweet, and in a Swimming VS Walking splatfest, Trouter and Berry would be on team swimming and Lunulata and Flap would be on team walk. Y'know how Deep Cut has solo versions of Anarchy Rainbow and people mashup them a lot? In each splatfest there would two combinations of the solos of the idols, making different splatfests have different songs(still, there is gonna be a main theme like anarchy rainbow and etc). Like imagine it shiver was on the same team as frye per example since they have themes that you can conceptualize better, it would be a mix of frye and shiver's theme and they'd dance together, or shiver with big man would be a mix of their solos too, so you can hear different combinations.

The way Flap sings in inspired in Xhosa, so he does clicks when he speaks and sings, I reccomend you look a bit into Xhosa as it's a beutiful language.

Their japanese names are: (I made the names myself too)

Flap メン(men）

Lunulata ヒョウモン(hyoumon)

Berry イチゴ(ichigo)

Trouter ヤマメ(yamame)

I could explain in detail their names but the wall is already too much text...
