Realistic Cream Effect/Animation

How do I get the realistic cream feeling in this short video you see? The cream object merging very smoothly with the previous cream part as long as it is held down on the screen. Is there any technique that I need to know in Unity or any information you think could make my job easier?

I do not have much experience in Unity and I try to learn day by day. I have a hard time developing such specific things because I cannot find what technique is used.

Thank you!
