- But nightmare dumbo octopus could be cthuluphant. How could you not want that?

We definitely need more sea creature pets (not experiments). A jellyfish would not be my first choice personally, though if done right you can have some beautiful options (even without it having a face). And what's wrong with having a faceless pet anyway? It would certainly be unique!
I could see a jellyfish experiment maybe but not an official pet as they have practically no structure and no face o.o

I'm not gonna judge a jelly for not having a face. They can still contribute to society!
Theraphos the problem is that there's almost no shape or structure or face to really make a pet and various colours for it. A pet needs to have some sort of shape to be able to earn that place in the pet world.

If we're talking tentacled sea creatures I'm throwing my vote in for a squid or an octopus, but jellyfish are cool too.

I don't think it matters that they don't have a facial structure. Liberties can be taken. It could have an actual face or it could have markings that just look like a face.
I like the ones with the ruffles.
The ruffles is the one I was imagining for a pet ! Those are my favorite jellyfish.
&I'm not hating on people's opinions when I say this, but not having a face originally ? So what ? It's called imagination and if a designer can't make that work, that's really sad /: (Not trying to step on anyone's toes btw)
