FLOOLINGS:

Floolings are the cousins to the jellyfish in splatoon and are jelly like humanoid creatures they have the same abilities and traits as inklings and octolings

they thrive in underwater environments (obviously in matches they would sink other then drown but still die

LORE:
they are a forgotten species that recently emerged from the ocean confused by everything new and one flooling seeked refugee in the squid beak splatoon and became a member

the strange burst of them appearing on land in inkopolis and the splatlands alerted the news thinking they came to attack the lively hood when they simply were curious

that’s all I got

(side note I’ll make more customisation such as hairstyles and styles for the little jelly on top of they’re heads)
