A.K.A Jelly
Roommate to Ika the squid, Jelly is a jellyfish inkling. They identify as genderless, just like jellyfishes usually are.
With a knack for dressing fancy and stalking, they're pretty good with stealth. It would be useful in ink battles, but they're actually banned from participating in ink fights. That's because they end up electrocuting the ink they're in. The tentacles from their back are mainly to blame. They conduct electricity when they're excited and it's harder to get them to stop. But it's not a problem, Ika actually likes battling Jelly. They prove to be a challenge.
Jelly is fond of stalking. As bad as it sounds, they're actually the good kind of stalker. they're completely Apothisexual, so nothing would ever happen really. they just like sneaking into people's houses and taking pictures of them when either they least expect it or when it's obvious. The one they takes the most photos of is Ika. It doesn't help that they're roommates.
Jelly doesn't take off their masks for some reason. When asked about it, they'll somehow avoid the question. After many years of trying and failing, Ika finally gave up on removing Jelly's mask. But Jelly did tell him a bit of why they keep it on. It's so people don't recognize them. Who exactly Jelly never elaborated on, but that was enough for Ika. Despite their odd way of doing things and their many MANY quirks, they're a goodish roommate to Ika and he's kind of an ok roommate to Jelly.
