Mimicking anything liquid in Unity is tough. Fluid simulations are not something Unity really does well if at all. I think the best solution at the moment would be to try to recreate it in a 3d program like Blender then bake out an animation or simulation that could be used in Unity. You could also sculpt out various tube waves in Blender, then apply a fancy shader that “fills” the mesh with a water effect to look like it’s growing over time. I haven’t deal much with water physics or shaders so my advice on that would be limited.
