InkJet from Splatoon how would you replicate it?

Hi, Im just asking a lot of questions around here lately and I cannot be stopped :stuck_out_tongue:

And my question this time is how the devil can I recreate the InkJet fx from splatoon

I cant even tell whether this is a mesh particle or billboards, nor how they managed to shoot this out of a particle system.

The reason Im asking this is not because I want to replicate the same thing, but instead I want to shoot a constant stream of water from the hands, that can be controlled, like a flamethrower in videogames.

As the only reference I got besides Super Mario Sunshine was splatoon, I thought this was the appropriate reference for my goal

If yall can help me out Id be over the moon :slightly_smiling_face:
