How can I animate something being constructed? I'm trying to animate something like a wall being created out of the ground.

Like this, per example:

What I want is to make the ice appear (being stacked and you can see is it forming into a "puddle" like) on the ground first.

Being created like this


Followed by the walls being pushed out of the ice in order to create the wall.

Can anyone tell me how can I do that?
If your "wall", as in the first picture, is "icy" meaning that it should grow from something like "water", another approach could use a reversed fluid animation, maybe:



You could use better (reverse) "start" shapes, and/or add displacements to final result, and also animate materials/textures to make the  fluid > solid transition modify the final shape, adding more interesting details...
