Make an object disappear in 1/4 pieces,I am working on a 2D game and when my pkayer touches the object I would like yo make it disappear. But in smaller pieces.

I am working on a 2D game andhave square objects representing the ground. When the user drills on an object I would like instead of making the entire object disappear at once I would like to make it vanish in about 1/4 peaces. Creating the drilling illusion to the player.,The object is a Square. And instead of just deleting it as a whole. I would like to create an illusion to the player as if it was disappearing in 1/4 pieces. Thanks
